CVE-2025-50434 (published 2025-08-19 16:15:28.043000+00:00)
A security issue has been identified in Appian Enterprise Business Process Management version 25.3. The vulnerability is related to incorrect access control, which under certain conditions could allow unauthorized access to information. NOTE: this has been disputed because the CVE Record information does not originate from the Supplier, and the report lacks specificity about why a problem exists, how the behavior could be reproduced, and whether any action could be taken to resolve the problem.
CVE-2025-51539 (published 2025-08-19 16:15:28.560000+00:00)
EzGED3 3.5.0 contains an unauthenticated arbitrary file read vulnerability due to improper access control and insufficient input validation in a script exposed via the web interface. A remote attacker can supply a crafted path parameter to a PHP script to read arbitrary files from the filesystem. The script lacks both authentication checks and secure path handling, allowing directory traversal attacks (e.g., ../../../) to access sensitive files such as configuration files, database dumps, source code, and password reset tokens. If phpMyAdmin is exposed, extracted credentials can be used for direct administrative access. In environments without such tools, attacker-controlled file reads still allow full database extraction by targeting raw MySQL data files. The vendor states that the issue is fixed in 3.5.72.27183.
CVE-2025-51540 (published 2025-08-19 16:15:28.720000+00:00)
EzGED3 3.5.0 stores user passwords using an insecure hashing scheme: md5(md5(password)). This hashing method is cryptographically weak and allows attackers to perform efficient offline brute-force attacks if password hashes are disclosed. The lack of salting and use of a fast, outdated algorithm makes it feasible to recover plaintext credentials using precomputed tables or GPU-based cracking tools. The vendor states that the issue is fixed in 3.5.72.27183.
CVE-2025-9145 (published 2025-08-19 16:15:29.470000+00:00)
A security vulnerability has been detected in Scada-LTS 2.7.8.1. This issue affects some unknown processing of the file view_edit.shtm of the component SVG File Handler. Such manipulation of the argument backgroundImageMP leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed publicly and may be used.
CVE-2025-9146 (published 2025-08-19 16:15:29.700000+00:00)
A flaw has been found in Linksys E5600 1.1.0.26. The affected element is the function verify_gemtek_header of the file checkFw.sh of the component Firmware Handler. Executing manipulation can lead to risky cryptographic algorithm. The attack may be launched remotely. The attack requires a high level of complexity. The exploitability is described as difficult. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2025-38554 (published 2025-08-19 17:15:31.510000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

mm: fix a UAF when vma->mm is freed after vma->vm_refcnt got dropped

By inducing delays in the right places, Jann Horn created a reproducer for
a hard to hit UAF issue that became possible after VMAs were allowed to be
recycled by adding SLAB_TYPESAFE_BY_RCU to their cache.

Race description is borrowed from Jann's discovery report:
lock_vma_under_rcu() looks up a VMA locklessly with mas_walk() under
rcu_read_lock().  At that point, the VMA may be concurrently freed, and it
can be recycled by another process.  vma_start_read() then increments the
vma->vm_refcnt (if it is in an acceptable range), and if this succeeds,
vma_start_read() can return a recycled VMA.

In this scenario where the VMA has been recycled, lock_vma_under_rcu()
will then detect the mismatching ->vm_mm pointer and drop the VMA through
vma_end_read(), which calls vma_refcount_put().  vma_refcount_put() drops
the refcount and then calls rcuwait_wake_up() using a copy of vma->vm_mm. 
This is wrong: It implicitly assumes that the caller is keeping the VMA's
mm alive, but in this scenario the caller has no relation to the VMA's mm,
so the rcuwait_wake_up() can cause UAF.

The diagram depicting the race:
T1         T2         T3
==         ==         ==
lock_vma_under_rcu
  mas_walk
          <VMA gets removed from mm>
                      mmap
                        <the same VMA is reallocated>
  vma_start_read
    __refcount_inc_not_zero_limited_acquire
                      munmap
                        __vma_enter_locked
                          refcount_add_not_zero
  vma_end_read
    vma_refcount_put
      __refcount_dec_and_test
                          rcuwait_wait_event
                            <finish operation>
      rcuwait_wake_up [UAF]

Note that rcuwait_wait_event() in T3 does not block because refcount was
already dropped by T1.  At this point T3 can exit and free the mm causing
UAF in T1.

To avoid this we move vma->vm_mm verification into vma_start_read() and
grab vma->vm_mm to stabilize it before vma_refcount_put() operation.

In the Linux kernel, the following vulnerability has been resolved:

HID: core: Harden s32ton() against conversion to 0 bits

Testing by the syzbot fuzzer showed that the HID core gets a
shift-out-of-bounds exception when it tries to convert a 32-bit
quantity to a 0-bit quantity.  Ideally this should never occur, but
there are buggy devices and some might have a report field with size
set to zero; we shouldn't reject the report or the device just because
of that.

Instead, harden the s32ton() routine so that it returns a reasonable
result instead of crashing when it is called with the number of bits
set to 0 -- the same as what snto32() does.

HID: apple: validate feature-report field count to prevent NULL pointer dereference

A malicious HID device with quirk APPLE_MAGIC_BACKLIGHT can trigger a NULL
pointer dereference whilst the power feature-report is toggled and sent to
the device in apple_magic_backlight_report_set(). The power feature-report
is expected to have two data fields, but if the descriptor declares one
field then accessing field[1] and dereferencing it in
apple_magic_backlight_report_set() becomes invalid
since field[1] will be NULL.

An example of a minimal descriptor which can cause the crash is something
like the following where the report with ID 3 (power report) only
references a single 1-byte field. When hid core parses the descriptor it
will encounter the final feature tag, allocate a hid_report (all members
of field[] will be zeroed out), create field structure and populate it,
increasing the maxfield to 1. The subsequent field[1] access and
dereference causes the crash.

In the Linux kernel, the following vulnerability has been resolved:

x86/sev: Evict cache lines during SNP memory validation

An SNP cache coherency vulnerability requires a cache line eviction
mitigation when validating memory after a page state change to private.
The specific mitigation is to touch the first and last byte of each 4K
page that is being validated. There is no need to perform the mitigation
when performing a page state change to shared and rescinding validation.

CPUID bit Fn8000001F_EBX[31] defines the COHERENCY_SFW_NO CPUID bit
that, when set, indicates that the software mitigation for this
vulnerability is not needed.

Implement the mitigation and invoke it when validating memory (making it
private) and the COHERENCY_SFW_NO bit is not set, indicating the SNP
guest is vulnerable.

CVE-2025-38563 (published 2025-08-19 17:15:32.790000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

perf/core: Prevent VMA split of buffer mappings

The perf mmap code is careful about mmap()'ing the user page with the
ringbuffer and additionally the auxiliary buffer, when the event supports
it. Once the first mapping is established, subsequent mapping have to use
the same offset and the same size in both cases. The reference counting for
the ringbuffer and the auxiliary buffer depends on this being correct.

Though perf does not prevent that a related mapping is split via mmap(2),
munmap(2) or mremap(2). A split of a VMA results in perf_mmap_open() calls,
which take reference counts, but then the subsequent perf_mmap_close()
calls are not longer fulfilling the offset and size checks. This leads to
reference count leaks.

As perf already has the requirement for subsequent mappings to match the
initial mapping, the obvious consequence is that VMA splits, caused by
resizing of a mapping or partial unmapping, have to be prevented.

Implement the vm_operations_struct::may_split() callback and return
unconditionally -EINVAL.

That ensures that the mapping offsets and sizes cannot be changed after the
fact. Remapping to a different fixed address with the same size is still
possible as it takes the references for the new mapping and drops those of
the old mapping.
CVE-2025-38564 (published 2025-08-19 17:15:32.933000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

perf/core: Handle buffer mapping fail correctly in perf_mmap()

After successful allocation of a buffer or a successful attachment to an
existing buffer perf_mmap() tries to map the buffer read only into the page
table. If that fails, the already set up page table entries are zapped, but
the other perf specific side effects of that failure are not handled.  The
calling code just cleans up the VMA and does not invoke perf_mmap_close().

This leaks reference counts, corrupts user->vm accounting and also results
in an unbalanced invocation of event::event_mapped().

Cure this by moving the event::event_mapped() invocation before the
map_range() call so that on map_range() failure perf_mmap_close() can be
invoked without causing an unbalanced event::event_unmapped() call.

perf_mmap_close() undoes the reference counts and eventually frees buffers.
CVE-2025-38565 (published 2025-08-19 17:15:33.077000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

perf/core: Exit early on perf_mmap() fail

When perf_mmap() fails to allocate a buffer, it still invokes the
event_mapped() callback of the related event. On X86 this might increase
the perf_rdpmc_allowed reference counter. But nothing undoes this as
perf_mmap_close() is never called in this case, which causes another
reference count leak.

Return early on failure to prevent that.

In the Linux kernel, the following vulnerability has been resolved:

sunrpc: fix handling of server side tls alerts

Scott Mayhew discovered a security exploit in NFS over TLS in
tls_alert_recv() due to its assumption it can read data from
the msg iterator's kvec..

kTLS implementation splits TLS non-data record payload between
the control message buffer (which includes the type such as TLS
aler or TLS cipher change) and the rest of the payload (say TLS
alert's level/description) which goes into the msg payload buffer.

This patch proposes to rework how control messages are setup and
used by sock_recvmsg().

If no control message structure is setup, kTLS layer will read and
process TLS data record types. As soon as it encounters a TLS control
message, it would return an error. At that point, NFS can setup a
kvec backed msg buffer and read in the control message such as a
TLS alert. Msg iterator can advance the kvec pointer as a part of
the copy process thus we need to revert the iterator before calling
into the tls_alert_recv.

In the Linux kernel, the following vulnerability has been resolved:

nfsd: avoid ref leak in nfsd_open_local_fh()

If two calls to nfsd_open_local_fh() race and both successfully call
nfsd_file_acquire_local(), they will both get an extra reference to the
net to accompany the file reference stored in *pnf.

One of them will fail to store (using xchg()) the file reference in
*pnf and will drop that reference but WON'T drop the accompanying
reference to the net.  This leak means that when the nfs server is shut
down it will hang in nfsd_shutdown_net() waiting for
&nn->nfsd_net_free_done.

This patch adds the missing nfsd_net_put().

TC_QOPT_MAX_QUEUE (16). This leads to a 4-byte out-of-bounds stack

Fix this by changing the policy to allow only up to TC_QOPT_MAX_QUEUE - 1.

pptp: ensure minimal skb length in pptp_xmit()

Commit aabc6596ffb3 ("net: ppp: Add bound checking for skb data

We need a similar fix in pptp_xmit(), otherwise we might
read uninit data as reported by syzbot.

CVE-2025-38576 (published 2025-08-19 17:15:34.573000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

powerpc/eeh: Make EEH driver device hotplug safe

Multiple race conditions existed between the PCIe hotplug driver and the
EEH driver, leading to a variety of kernel oopses of the same general
nature:

<pcie device unplug>
<eeh driver trigger>
<hotplug removal trigger>
<pcie tree reconfiguration>
<eeh recovery next step>
<oops in EEH driver bus iteration loop>

A second class of oops is also seen when the underlying bus disappears
during device recovery.

Refactor the EEH module to be PCI rescan and remove safe.  Also clean
up a few minor formatting / readability issues.
CVE-2025-38579 (published 2025-08-19 17:15:35.020000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

f2fs: fix KMSAN uninit-value in extent_info usage

KMSAN reported a use of uninitialized value in `__is_extent_mergeable()`
 and `__is_back_mergeable()` via the read extent tree path.

The root cause is that `get_read_extent_info()` only initializes three
fields (`fofs`, `blk`, `len`) of `struct extent_info`, leaving the
remaining fields uninitialized. This leads to undefined behavior
when those fields are accessed later, especially during
extent merging.

Fix it by zero-initializing the `extent_info` struct before population.
CVE-2025-38580 (published 2025-08-19 17:15:35.160000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

ext4: fix inode use after free in ext4_end_io_rsv_work()

In ext4_io_end_defer_completion(), check if io_end->list_vec is empty to
avoid adding an io_end that requires no conversion to the
i_rsv_conversion_list, which in turn prevents starting an unnecessary
worker. An ext4_emergency_state() check is also added to avoid attempting
to abort the journal in an emergency state.

Additionally, ext4_put_io_end_defer() is refactored to call
ext4_io_end_defer_completion() directly instead of being open-coded.
This also prevents starting an unnecessary worker when EXT4_IO_END_FAILED
is set but data_err=abort is not enabled.

This ensures that the check in ext4_put_io_end_defer() is consistent with
the check in ext4_end_bio(). Otherwise, we might add an io_end to the
i_rsv_conversion_list and then call ext4_finish_bio(), after which the
inode could be freed before ext4_end_io_rsv_work() is called, triggering
a use-after-free issue.

In the Linux kernel, the following vulnerability has been resolved:

padata: Fix pd UAF once and for all

There is a race condition/UAF in padata_reorder that goes back
to the initial commit.  A reference count is taken at the start
of the process in padata_do_parallel, and released at the end in
padata_serial_worker.

This reference count is (and only is) required for padata_replace
to function correctly.  If padata_replace is never called then
there is no issue.

In the function padata_reorder which serves as the core of padata,
as soon as padata is added to queue->serial.list, and the associated
spin lock released, that padata may be processed and the reference
count on pd would go away.

Fix this by getting the next padata before the squeue->serial lock
is released.

In order to make this possible, simplify padata_reorder by only
calling it once the next padata arrives.
CVE-2025-38585 (published 2025-08-19 17:15:35.877000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

staging: media: atomisp: Fix stack buffer overflow in gmin_get_var_int()

When gmin_get_config_var() calls efi.get_variable() and the EFI variable
is larger than the expected buffer size, two behaviors combine to create
a stack buffer overflow:

1. gmin_get_config_var() does not return the proper error code when
   efi.get_variable() fails. It returns the stale 'ret' value from
   earlier operations instead of indicating the EFI failure.

2. When efi.get_variable() returns EFI_BUFFER_TOO_SMALL, it updates
   *out_len to the required buffer size but writes no data to the output
   buffer. However, due to bug #1, gmin_get_var_int() believes the call
   succeeded.

The caller gmin_get_var_int() then performs:
- Allocates val[CFG_VAR_NAME_MAX + 1] (65 bytes) on stack
- Calls gmin_get_config_var(dev, is_gmin, var, val, &len) with len=64
- If EFI variable is >64 bytes, efi.get_variable() sets len=required_size
- Due to bug #1, thinks call succeeded with len=required_size
- Executes val[len] = 0, writing past end of 65-byte stack buffer

This creates a stack buffer overflow when EFI variables are larger than
64 bytes. Since EFI variables can be controlled by firmware or system
configuration, this could potentially be exploited for code execution.

Fix the bug by returning proper error codes from gmin_get_config_var()
based on EFI status instead of stale 'ret' value.

The gmin_get_var_int() function is called during device initialization
for camera sensor configuration on Intel Bay Trail and Cherry Trail
platforms using the atomisp camera stack.
CVE-2025-38586 (published 2025-08-19 17:15:36.113000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

bpf, arm64: Fix fp initialization for exception boundary

In the ARM64 BPF JIT when prog->aux->exception_boundary is set for a BPF
program, find_used_callee_regs() is not called because for a program
acting as exception boundary, all callee saved registers are saved.
find_used_callee_regs() sets `ctx->fp_used = true;` when it sees FP
being used in any of the instructions.

For programs acting as exception boundary, ctx->fp_used remains false
even if frame pointer is used by the program and therefore, FP is not
set-up for such programs in the prologue. This can cause the kernel to
crash due to a pagefault.

Fix it by setting ctx->fp_used = true for exception boundary programs as
fp is always saved in such programs.

ipv6: fix possible infinite loop in fib6_info_uses_dev()

fib6_info_uses_dev() seems to rely on RCU without an explicit
protection.

Like the prior fix in rt6_nlmsg_size(),
we need to make sure fib6_del_route() or fib6_add_rt2node()
have not removed the anchor from the list, or we risk an infinite loop.
CVE-2025-38588 (published 2025-08-19 17:15:36.383000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

ipv6: prevent infinite loop in rt6_nlmsg_size()

While testing prior patch, I was able to trigger
an infinite loop in rt6_nlmsg_size() in the following place:

list_for_each_entry_rcu(sibling, &f6i->fib6_siblings,
			fib6_siblings) {
	rt6_nh_nlmsg_size(sibling->fib6_nh, &nexthop_len);
}

This is because fib6_del_route() and fib6_add_rt2node()
uses list_del_rcu(), which can confuse rcu readers,
because they might no longer see the head of the list.

Restart the loop if f6i->fib6_nsiblings is zero.

In the Linux kernel, the following vulnerability has been resolved:

neighbour: Fix null-ptr-deref in neigh_flush_dev().

kernel test robot reported null-ptr-deref in neigh_flush_dev(). [0]

The cited commit introduced per-netdev neighbour list and converted
neigh_flush_dev() to use it instead of the global hash table.

One thing we missed is that neigh_table_clear() calls neigh_ifdown()
with NULL dev.

Let's restore the hash table iteration.

Note that IPv6 module is no longer unloadable, so neigh_table_clear()
is called only when IPv6 fails to initialise, which is unlikely to
happen.

CVE-2025-38591 (published 2025-08-19 17:15:36.790000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

bpf: Reject narrower access to pointer ctx fields

The following BPF program, simplified from a syzkaller repro, causes a
kernel warning:

    r0 = *(u8 *)(r1 + 169);
    exit;

With pointer field sk being at offset 168 in __sk_buff. This access is
detected as a narrower read in bpf_skb_is_valid_access because it
doesn't match offsetof(struct __sk_buff, sk). It is therefore allowed
and later proceeds to bpf_convert_ctx_access. Note that for the
"is_narrower_load" case in the convert_ctx_accesses(), the insn->off
is aligned, so the cnt may not be 0 because it matches the
offsetof(struct __sk_buff, sk) in the bpf_convert_ctx_access. However,
the target_size stays 0 and the verifier errors with a kernel warning:

    verifier bug: error during ctx access conversion(1)

This patch fixes that to return a proper "invalid bpf_context access
off=X size=Y" error on the load instruction.

The same issue affects multiple other fields in context structures that
allow narrow access. Some other non-affected fields (for sk_msg,
sk_lookup, and sockopt) were also changed to use bpf_ctx_range_ptr for
consistency.

Note this syzkaller crash was reported in the "Closes" link below, which
used to be about a different bug, fixed in
commit fce7bd8e385a ("bpf/verifier: Handle BPF_LOAD_ACQ instructions
in insn_def_regno()"). Because syzbot somehow confused the two bugs,
the new crash and repro didn't get reported to the mailing list.

Function 'hci_discovery_filter_clear()' frees 'uuids' array and then
sets it to NULL. There is a tiny chance of the following race:

'hci_cmd_sync_work()'

 'update_passive_scan_sync()'

   'hci_update_passive_scan_sync()'

     'hci_discovery_filter_clear()'
       kfree(uuids);

       <-------------------------preempted-------------------------------->
                                           'start_service_discovery()'

                                             'hci_discovery_filter_clear()'
                                               kfree(uuids); // DOUBLE FREE

       <-------------------------preempted-------------------------------->

      uuids = NULL;

To fix it let's add locking around 'kfree()' call and NULL pointer
assignment. Otherwise the following backtrace fires:

CVE-2025-38594 (published 2025-08-19 17:15:37.213000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

iommu/vt-d: Fix UAF on sva unbind with pending IOPFs

Commit 17fce9d2336d ("iommu/vt-d: Put iopf enablement in domain attach
path") disables IOPF on device by removing the device from its IOMMU's
IOPF queue when the last IOPF-capable domain is detached from the device.
Unfortunately, it did this in a wrong place where there are still pending
IOPFs. As a result, a use-after-free error is potentially triggered and
eventually a kernel panic with a kernel trace similar to the following:

 refcount_t: underflow; use-after-free.

The intel_pasid_tear_down_entry() function is responsible for blocking
hardware from generating new page faults and flushing all in-flight
ones. Therefore, moving iopf_for_domain_remove() after this function
should resolve this.
CVE-2025-38595 (published 2025-08-19 17:15:37.343000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

xen: fix UAF in dmabuf_exp_from_pages()

[dma_buf_fd() fixes; no preferences regarding the tree it goes through -
up to xen folks]

As soon as we'd inserted a file reference into descriptor table, another
thread could close it.  That's fine for the case when all we are doing is
returning that descriptor to userland (it's a race, but it's a userland
race and there's nothing the kernel can do about it).  However, if we
follow fd_install() with any kind of access to objects that would be
destroyed on close (be it the struct file itself or anything destroyed
by its ->release()), we have a UAF.

dma_buf_fd() is a combination of reserving a descriptor and fd_install().
gntdev dmabuf_exp_from_pages() calls it and then proceeds to access the
objects destroyed on close - starting with gntdev_dmabuf itself.

Fix that by doing reserving descriptor before anything else and do
fd_install() only when everything had been set up.
CVE-2025-38596 (published 2025-08-19 17:15:37.480000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

drm/panthor: Fix UAF in panthor_gem_create_with_handle() debugfs code

The object is potentially already gone after the drm_gem_object_put().
In general the object should be fully constructed before calling
drm_gem_handle_create(), except the debugfs tracking uses a separate
lock and list and separate flag to denotate whether the object is
actually initialized.

Since I'm touching this all anyway simplify this by only adding the
object to the debugfs when it's ready for that, which allows us to
delete that separate flag. panthor_gem_debugfs_bo_rm() already checks
whether we've actually been added to the list or this is some error
path cleanup.

CVE-2025-38597 (published 2025-08-19 17:15:37.613000+00:00)
In the Linux kernel, the following vulnerability has been resolved:

drm/rockchip: vop2: fail cleanly if missing a primary plane for a video-port

Each window of a vop2 is usable by a specific set of video ports, so while
binding the vop2, we look through the list of available windows trying to
find one designated as primary-plane and usable by that specific port.

The code later wants to use drm_crtc_init_with_planes with that found
primary plane, but nothing has checked so far if a primary plane was
actually found.

For whatever reason, the rk3576 vp2 does not have a usable primary window
(if vp0 is also in use) which brought the issue to light and ended in a
null-pointer dereference further down.

As we expect a primary-plane to exist for a video-port, add a check at
the end of the window-iteration and fail probing if none was found.

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath11k: clear initialized flag for deinit-ed srng lists

In a number of cases we see kernel panics on resume due
to ath11k kernel page fault, which happens under the
following circumstances:

1) First ath11k_hal_dump_srng_stats() call

 Last interrupt received for each group:
 ath11k_pci 0000:01:00.0: group_id 0 22511ms before
 ath11k_pci 0000:01:00.0: group_id 1 14440788ms before

 ath11k_pci 0000:01:00.0: Service connect timeout

 ath11k_pci 0000:01:00.0: already resetting count 2
 ath11k_pci 0000:01:00.0: failed to wait wlan mode request (mode 4): -110
 ath11k_pci 0000:01:00.0: qmi failed to send wlan mode off: -110
 ath11k_pci 0000:01:00.0: failed to reconfigure driver on crash recovery
 [..]

2) At this point reconfiguration fails (we have 2 resets) and
  ath11k_core_reconfigure_on_crash() calls ath11k_hal_srng_deinit()
  which destroys srng lists.  However, it does not reset per-list
  ->initialized flag.

3) Second ath11k_hal_dump_srng_stats() call sees stale ->initialized
  flag and attempts to dump srng stats:
