dm: Always split write BIOs to zoned device limits
CVE: CVE-2025-39792
Component: kernel
CWE: CWE-833
Severity: Moderate
CVSS v3: 5.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H
Release date: 2025-09-12T00:00:00+00:00

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

dm: Always split write BIOs to zoned device limits

Any zoned DM target that requires zone append emulation will use the
block layer zone write plugging. In such case, DM target drivers must
not split BIOs using dm_accept_partial_bio() as doing so can potentially
lead to deadlocks with queue freeze operations. Regular write operations
used to emulate zone append operations also cannot be split by the
target driver as that would result in an invalid writen sector value
return using the BIO sector.

In order for zoned DM target drivers to avoid such incorrect BIO
splitting, we must ensure that large BIOs are split before being passed
to the map() function of the target, thus guaranteeing that the
limits for the mapped device are not exceeded.

dm-crypt and dm-flakey are the only target drivers supporting zoned
devices and using dm_accept_partial_bio().

In the case of dm-crypt, this function is used to split BIOs to the
internal max_write_size limit (which will be suppressed in a different
patch). However, since crypt_alloc_buffer() uses a bioset allowing only
up to BIO_MAX_VECS (256) vectors in a BIO. The dm-crypt device
max_segments limit, which is not set and so default to BLK_MAX_SEGMENTS
(128), must thus be respected and write BIOs split accordingly.

In the case of dm-flakey, since zone append emulation is not required,
the block layer zone write plugging is not used and no splitting of BIOs
required.

Modify the function dm_zone_bio_needs_split() to use the block layer
helper function bio_needs_zone_write_plugging() to force a call to
bio_split_to_limits() in dm_split_and_process_bio(). This allows DM
target drivers to avoid using dm_accept_partial_bio() for write
operations on zoned DM devices.

Statement: This vulnerability is rated Moderate for Red Hat Enterprise Linux 9 and 10, and Red Hat In-Vehicle OS. It affects the Linux kernel's device mapper (dm) subsystem, where improper handling of write BIOs to zoned devices can lead to a deadlock. Exploitation requires high privileges and local access to a system configured with zoned DM targets. Triggering this vulnerability requires elevated privileges like `CAP_NET_ADMIN` to be able to create/manage dm devices. 

Red Hat Enterprise Linux 7 and 8 are not affected as the vulnerable code is not present.

CVE: CVE-2025-22074
Component: kernel
Severity: None
Release date: 2025-04-16T00:00:00+00:00

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

ksmbd: fix r_count dec/increment mismatch

r_count is only increased when there is an oplock break wait,
so r_count inc/decrement are not paired. This can cause r_count
to become negative, which can lead to a problem where the ksmbd
thread does not terminate.

Severity: Low
CVSS v3: 5.6/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Release date: 2025-12-16T00:00:00+00:00

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

usb: storage: Fix memory leak in USB bulk transport

A kernel memory leak was identified by the 'ioctl_sg01' test from Linux
Test Project (LTP). The following bytes were mainly observed: 0x53425355.

When USB storage devices incorrectly skip the data phase with status data,
the code extracts/validates the CSW from the sg buffer, but fails to clear
it afterwards. This leaves status protocol data in srb's transfer buffer,
such as the US_BULK_CS_SIGN 'USBS' signature observed here. Thus, this can
lead to USB protocols leaks to user space through SCSI generic (/dev/sg*)
interfaces, such as the one seen here when the LTP test requested 512 KiB.

Fix the leak by zeroing the CSW data in srb's transfer buffer immediately
after the validation of devices that skip data phase.

Note: Differently from CVE-2018-1000204, which fixed a big leak by zero-
ing pages at allocation time, this leak occurs after allocation, when USB
protocol data is written to already-allocated sg pages.

  lock: terminate_lock.2+0x0/0x1c, .magic: dead4ead, .owner: ifconfig/2420, .owner_cpu: 0

While creating the stack trace, the unwinder uses the stack pointer to guess
the previous frame to read the previous stack pointer from memory.  The crash
happens, because the unwinder tries to read from unaligned memory and as such
triggers the unalignment trap handler which then leads to the spinlock
recursion and finally to a deadlock.

Fix it by checking the alignment before accessing the memory.

NULL pointer dereference in show_vty_ext_link_lan_adj_sid() in ospf_ext.c
CVE: CVE-2025-61103
Component: frr
CWE: CWE-476
Severity: Moderate

Release date: 2025-10-28T00:00:00+00:00

A flaw was found in frr. When the OSPF daemon (ospfd) is configured with the debug command "debug ospf packet all send/recv detail", it attempts to print detailed information about OSPF packets. However, a specially crafted OSPF packet can trigger a NULL pointer dereference in the show_vty_ext_link_lan_adj_sid function in the ospf_ext.c file, causing the OSPF process to crash and resulting in a denial of service.

Statement: A very specific and non-default runtime configuration is required to exploit this flaw. The vulnerable code is only reachable when OSPF detailed packet debugging is enabled (debug ospf packet all send/recv detail), which is typically used for temporary diagnostic purposes and not in production environments. In normal operation, the affected function is not invoked, thereby significantly reducing exposure.
Furthermore, this flaw can trigger a NULL pointer dereference, causing a crash of the ospfd process without memory corruption or any other security impact.

A NULL pointer dereference can occur in tcp_ao_finish_connect() during a

enabled.

The function is called with skb being NULL and attempts to dereference it
on tcp_hdr(skb)->seq without a prior skb validation.

Fix this by checking if skb is NULL before dereferencing it.

The commentary is taken from bpf_skops_established(), which is also called
in the same flow. Unlike the function being patched,
bpf_skops_established() validates the skb before dereferencing it.

ip4_dst_hoplimit() can use dst_dev_net_rcu().

Statement: Several paths read dst->dev without RCU. A concurrent dst/device teardown could cause a use-after-free—fixed by switching to dst_dev_rcu() and wrapping sections in rcu_read_lock(), mitigating a local DoS/LPE risk.
A local user floods route changes (device up/down, MTU/GSO tweaks, dst churn) while rapidly creating sockets, racing sk_setup_caps() to read dev after free that leads to kernel crash.
