[/INST] 'cwe': ['CWE-416'], 'message': 'p54usb: Fix race between disconnect and firmware loading
The syzbot fuzzer found a bug in the p54 USB wireless driver. The
issue involves a race between disconnect and the firmware-loader
callback routine, and it has several aspects.
One big problem is that when the firmware can't be loaded, the
callback routine tries to unbind the driver from the USB _device_ (by
calling device_release_driver) instead of from the USB _interface_ to
which it is actually bound (by calling usb_driver_release_interface).
The race involves access to the private data structure. The driver's
disconnect handler waits for a completion that is signalled by the
firmware-loader callback routine. As soon as the completion is
signalled, you have to assume that the private data structure may have
been deallocated by the disconnect handler -- even if the firmware was
loaded without errors. However, the callback routine does access the
private data several times after that point.
Another problem is that, in order to ensure that the USB device
structure hasn't been freed when the callback routine runs, the driver
takes a reference to it. This isn't good enough any more, because now
that the callback routine calls usb_driver_release_interface, it has
to ensure that the interface structure hasn't been freed.
Finally, the driver takes an unnecessary reference to the USB device
structure in the probe function and drops the reference in the
disconnect handler. This extra reference doesn't accomplish anything,
because the USB core already guarantees that a device structure won't
be deallocated while a driver is still bound to any of its interfaces.
To fix these problems, this patch makes the following changes:
Call usb_driver_release_interface() rather than
device_release_driver().
Don't signal the completion until after the important
information has been copied out of the private data structure,
and don't refer to the private data at all thereafter.
Lock udev (the interface's parent) before unbinding the driver
instead of locking udev->parent.
During the firmware loading process, take a reference to the
USB interface instead of the USB device.
Don't take an unnecessary reference to the device during probe
(and then don't drop it during disconnect).

The current code performs the cancel of a delayed work at the late
stage of disconnection procedure, which may lead to the access to the

This patch assures to call cancel_delayed_work_sync() at the beginning
of the disconnection procedure for avoiding that race. The delayed
work object is now assigned in the common line6 object instead of its
derivative, so that we can call cancel_delayed_work_sync().
Along with the change, the startup function is called via the new

This works just fine in 1.14.0, where we call .open only once (so the
INFO and GO repeat calls into the same plugin handle), but in 1.14.1
it regressed into causing an assertion failure: we are now calling
.open a second time on a connection that is already opened:
$ nbdkit -rfv null &
$ hacked-qemu-io -f raw -r nbd://localhost -c quit
...
nbdkit: null[1]: debug: null: open readonly=1
nbdkit: backend.c:179: backend_open: Assertion `h->handle == NULL' failed.
Worse, on the mainline development, we have recently made it possible
for plugins to actively report different information for different
export names; for example, a plugin may choose to report different
answers for .can_write on export A than for export B; but if we share
cached handles, then an NBD_OPT_INFO on one export prevents correct
answers for NBD_OPT_GO on the second export name. (The HACK envvar in
my qemu modifications can be used to demonstrate cross-name requests,
which are even less likely in a real client).
The solution is to call .close after NBD_OPT_INFO, coupled with enough
glue logic to reset cached connection handles back to the state
expected by .open. This in turn means factoring out another backend_*
function, but also gives us an opportunity to change
backend_set_handle to no longer accept NULL.
The assertion failure is, to some extent, a possible denial of service
attack (one client can force nbdkit to exit by merely sending OPT_INFO
before OPT_GO, preventing the next client from connecting), although
this is mitigated by using TLS to weed out untrusted clients. Still,
the fact that we introduced a potential DoS attack while trying to fix
a traffic amplification security bug is not very nice.
Sadly, as there are no known clients that easily trigger this mode of
operation (OPT_INFO before OPT_GO), there is no easy way to cover this
via a testsuite addition. I may end up hacking something into libnbd.

interestingly, info on a different name), as a patch against qemu

This works just fine in 1.14.0, where we call .open only once (so the
INFO and GO repeat calls into the same plugin handle), but in 1.14.1
it regressed into causing an assertion failure: we are now calling
.open a second time on a connection that is already opened:
$ nbdkit -rfv null &
$ hacked-qemu-io -f raw -r nbd://localhost -c quit
...
nbdkit: null[1]: debug: null: open readonly=1
nbdkit: backend.c:179: backend_open: Assertion `h->handle == NULL' failed.
Worse, on the mainline development, we have recently made it possible
for plugins to actively report different information for different
export names; for example, a plugin may choose to report different
answers for .can_write on export A than for export B; but if we share
cached handles, then an NBD_OPT_INFO on one export prevents correct
answers for NBD_OPT_GO on the second export name. (The HACK envvar in
my qemu modifications can be used to demonstrate cross-name requests,
which are even less likely in a real client).
The solution is to call .close after NBD_OPT_INFO, coupled with enough
glue logic to reset cached connection handles back to the state
expected by .open. This in turn means factoring out another backend_*
function, but also gives us an opportunity to change
backend_set_handle to no longer accept NULL.
The assertion failure is, to some extent, a possible denial of service
attack (one client can force nbdkit to exit by merely sending OPT_INFO
before OPT_GO, preventing the next client from connecting), although
this is mitigated by using TLS to weed out untrusted clients. Still,
the fact that we introduced a potential DoS attack while trying to fix
a traffic amplification security bug is not very nice.
Sadly, as there are no known clients that easily trigger this mode of
operation (OPT_INFO before OPT_GO), there is no easy way to cover this
via a testsuite addition. I may end up hacking something into libnbd.

No backend.c in the stable branch, and less things to reset, so instead
ode that logic into filter_close.

[/INST] 'cwe': ['CWE-662'], 'message': 'powerpc/tm: Fix restoring FP/VMX facility incorrectly on interrupts
When in userspace and MSR FP=0 the hardware FP state is unrelated to
the current process. This is extended for transactions where if tbegin
is run with FP=0, the hardware checkpoint FP state will also be
unrelated to the current process. Due to this, we need to ensure this
hardware checkpoint is updated with the correct state before we enable
FP for this process.
Unfortunately we get this wrong when returning to a process from a
hardware interrupt. A process that starts a transaction with FP=0 can
take an interrupt. When the kernel returns back to that process, we
change to FP=1 but with hardware checkpoint FP state not updated. If
this transaction is then rolled back, the FP registers now contain the
wrong state.
The process looks like this:
Userspace: Kernel
Start userspace
with MSR FP=0 TM=1
< -----
...
tbegin
bne
Hardware interrupt
---- >
<do_IRQ...>
....
ret_from_except
restore_math()
/* sees FP=0 */
restore_fp()
tm_active_with_fp()
/* sees FP=1 (Incorrect) */
load_fp_state()
FP = 0 -> 1
< -----
Return to userspace
with MSR TM=1 FP=1
with junk in the FP TM checkpoint
TM rollback
reads FP junk
When returning from the hardware exception, tm_active_with_fp() is
incorrectly making restore_fp() call load_fp_state() which is setting
FP=1.
The fix is to remove tm_active_with_fp().
tm_active_with_fp() is attempting to handle the case where FP state
has been changed inside a transaction. In this case the checkpointed
and transactional FP state is different and hence we must restore the
FP state (ie. we can't do lazy FP restore inside a transaction that's
used FP). It's safe to remove tm_active_with_fp() as this case is
handled by restore_tm_state(). restore_tm_state() detects if FP has
been using inside a transaction and will set load_fp and call
restore_math() to ensure the FP state (checkpoint and transaction) is
restored.
This is a data integrity problem for the current process as the FP
registers are corrupted. It's also a security problem as the FP
registers from one process may be leaked to another.
Similarly for VMX.
A simple testcase to replicate this will be posted to
tools/testing/selftests/powerpc/tm/tm-poison.c
This fixes CVE-2019-15031.

If alloc_disk fails in pf_init_units, pf->disk will be
NULL, however in pf_detect and pf_exit, it's not check
this before free.It may result a NULL pointer dereference.
Also when register_blkdev failed, blk_cleanup_queue() and
blk_mq_free_tag_set() should be called to free resources.

[/INST] 'cwe': ['CWE-787'], 'message': 'TurboJPEG: Properly handle gigapixel images
Prevent several integer overflow issues and subsequent segfaults that
occurred when attempting to compress or decompress gigapixel images with
the TurboJPEG API:
- Modify tjBufSize(), tjBufSizeYUV2(), and tjPlaneSizeYUV() to avoid
integer overflow when computing the return values and to return an
error if such an overflow is unavoidable.
- Modify tjunittest to validate the above.
- Modify tjCompress2(), tjEncodeYUVPlanes(), tjDecompress2(), and
tjDecodeYUVPlanes() to avoid integer overflow when computing the row
pointers in the 64-bit TurboJPEG C API.
- Modify TJBench (both C and Java versions) to avoid overflowing the
size argument to malloc()/new and to fail gracefully if such an
overflow is unavoidable.
In general, this allows gigapixel images to be accommodated by the
64-bit TurboJPEG C API when using automatic JPEG buffer (re)allocation.
Such images cannot currently be accommodated without automatic JPEG
buffer (re)allocation, due to the fact that tjAlloc() accepts a 32-bit
integer argument (oops.) Such images cannot be accommodated in the
TurboJPEG Java API due to the fact that Java always uses a signed 32-bit
integer as an array index.

These files contain loops that convert system data into python objects

A recent fix addressing a deadlock on disconnect introduced a new bug
by moving the present flag out of the critical section protected by the
driver-data mutex. This could lead to a racing release() freeing the
driver data before disconnect() is done with it.
Due to insufficient locking a related use-after-free could be triggered
also before the above mentioned commit. Specifically, the driver needs
to hold the driver-data mutex also while checking the opened flag at
disconnect().

[/INST] 'cwe': ['CWE-362'], 'message': 'USB: core: Fix races in character device registration and deregistraion
The syzbot fuzzer has found two (!) races in the USB character device
registration and deregistration routines. This patch fixes the races.
The first race results from the fact that usb_deregister_dev() sets
usb_minors[intf->minor] to NULL before calling device_destroy() on the
class device. This leaves a window during which another thread can
allocate the same minor number but will encounter a duplicate name
error when it tries to register its own class device. A typical error
message in the system log would look like:
sysfs: cannot create duplicate filename '/class/usbmisc/ldusb0'
The patch fixes this race by destroying the class device first.
The second race is in usb_register_dev(). When that routine runs, it
first allocates a minor number, then drops minor_rwsem, and then
creates the class device. If the device creation fails, the minor
number is deallocated and the whole routine returns an error. But
during the time while minor_rwsem was dropped, there is a window in
which the minor number is allocated and so another thread can
successfully open the device file. Typically this results in
use-after-free errors or invalid accesses when the other thread closes
its open file reference, because the kernel then tries to release
resources that were already deallocated when usb_register_dev()
failed. The patch fixes this race by keeping minor_rwsem locked
throughout the entire routine.

[/INST] 'cwe': ['CWE-287'], 'message': 'mac80211: Do not send Layer 2 Update frame before authorization
The Layer 2 Update frame is used to update bridges when a station roams
to another AP even if that STA does not transmit any frames after the
reassociation. This behavior was described in IEEE Std 802.11F-2003 as
something that would happen based on MLME-ASSOCIATE.indication, i.e.,
before completing 4-way handshake. However, this IEEE trial-use
recommended practice document was published before RSN (IEEE Std
802.11i-2004) and as such, did not consider RSN use cases. Furthermore,
IEEE Std 802.11F-2003 was withdrawn in 2006 and as such, has not been
maintained amd should not be used anymore.
Sending out the Layer 2 Update frame immediately after association is
fine for open networks (and also when using SAE, FT protocol, or FILS
authentication when the station is actually authenticated by the time
association completes). However, it is not appropriate for cases where
RSN is used with PSK or EAP authentication since the station is actually
fully authenticated only once the 4-way handshake completes after
authentication and attackers might be able to use the unauthenticated
triggering of Layer 2 Update frame transmission to disrupt bridge
behavior.
Fix this by postponing transmission of the Layer 2 Update frame from
station entry addition to the point when the station entry is marked
authorized. Similarly, send out the VLAN binding update only if the STA
entry has already been authorized.

[/INST] 'cwe': ['CWE-400', 'CWE-703'], 'message': 'sched/fair: Fix low cpu usage with high throttling by removing expiration of cpu-local slices
It has been observed, that highly-threaded, non-cpu-bound applications
running under cpu.cfs_quota_us constraints can hit a high percentage of
periods throttled while simultaneously not consuming the allocated
amount of quota. This use case is typical of user-interactive non-cpu
bound applications, such as those running in kubernetes or mesos when
run on multiple cpu cores.
This has been root caused to cpu-local run queue being allocated per cpu
bandwidth slices, and then not fully using that slice within the period.
At which point the slice and quota expires. This expiration of unused
slice results in applications not being able to utilize the quota for
which they are allocated.
The non-expiration of per-cpu slices was recently fixed by
'commit 512ac999d275 ("sched/fair: Fix bandwidth timer clock drift
condition")'. Prior to that it appears that this had been broken since
at least 'commit 51f2176d74ac ("sched/fair: Fix unlocked reads of some
cfs_b->quota/period")' which was introduced in v3.16-rc1 in 2014. That
added the following conditional which resulted in slices never being
expired.
if (cfs_rq->runtime_expires != cfs_b->runtime_expires) {
/* extend local deadline, drift is bounded above by 2 ticks */
cfs_rq->runtime_expires += TICK_NSEC;
Because this was broken for nearly 5 years, and has recently been fixed
and is now being noticed by many users running kubernetes
(https://github.com/kubernetes/kubernetes/issues/67577) it is my opinion
that the mechanisms around expiring runtime should be removed
altogether.
This allows quota already allocated to per-cpu run-queues to live longer
than the period boundary. This allows threads on runqueues that do not
use much CPU to continue to use their remaining slice over a longer
period of time than cpu.cfs_period_us. However, this helps prevent the
above condition of hitting throttling while also not fully utilizing
your cpu quota.
This theoretically allows a machine to use slightly more than its
allotted quota in some periods. This overflow would be bounded by the
remaining quota left on each per-cpu runqueueu. This is typically no
more than min_cfs_rq_runtime=1ms per cpu. For CPU bound tasks this will
change nothing, as they should theoretically fully utilize all of their
quota in each period. For user-interactive tasks as described above this
provides a much better user/application experience as their cpu
utilization will more closely match the amount they requested when they
hit throttling. This means that cpu limits no longer strictly apply per
period for non-cpu bound applications, but that they are still accurate
over longer timeframes.
This greatly improves performance of high-thread-count, non-cpu bound
applications with low cfs_quota_us allocation on high-core-count
machines. In the case of an artificial testcase (10ms/100ms of quota on
80 CPU machine), this commit resulted in almost 30x performance
improvement, while still maintaining correct cpu quota restrictions.
That testcase is available at https://github.com/indeedeng/fibtest.

Define a mutex for the exclusive use of interacting with the per-file
context-idr, that was previously guarded by struct_mutex. This allows us
to reduce the coverage of struct_mutex, with a view to removing the last
bits coordinating GEM context later. (In the short term, we avoid taking
struct_mutex while using the extended constructor functions, preventing
some nasty recursion.)

UDP IPv6 packets auto flowlabels are using a 32bit secret
(static u32 hashrnd in net/core/flow_dissector.c) and
apply jhash() over fields known by the receivers.
Attackers can easily infer the 32bit secret and use this information
to identify a device and/or user, since this 32bit secret is only
set at boot time.
Really, using jhash() to generate cookies sent on the wire
is a serious security concern.
Trying to change the rol32(hash, 16) in ip6_make_flowlabel() would be
a dead end. Trying to periodically change the secret (like in sch_sfq.c)
could change paths taken in the network for long lived flows.
Let's switch to siphash, as we did in commit df453700e8d8
("inet: switch IP ID generator to siphash")
Using a cryptographically strong pseudo random function will solve this
privacy issue and more generally remove other weak points in the stack.
Packet schedulers using skb_get_hash_perturb() benefit from this change.

Final part of the fixes for CVE-2020-5208, see
https://github.com/ipmitool/ipmitool/security/advisories/GHSA-g659-9qxw-p7cp
9 variants of stack buffer overflow when parsing `id_string` field of
SDR records returned from `CMD_GET_SDR` command.
SDR record structs have an `id_code` field, and an `id_string` `char`
array.
The length of `id_string` is calculated as `(id_code & 0x1f) + 1`,
which can be larger than expected 16 characters (if `id_code = 0xff`,
then length will be `(0xff & 0x1f) + 1 = 32`).
In numerous places, this can cause stack buffer overflow when copying
into fixed buffer of size `17` bytes from this calculated length.'</s> |

Currently when qemu receives a vnc connect, it creates a 'VncState' to

data in 'vnc_async_encoding_start' and 'vnc_async_encoding_end'.
In 'zrle_compress_data' it calls 'deflateInit2' to allocate the libz library

'VncState'. In 'vnc_zrle_clear' it calls 'deflateEnd' to free the libz
library opaque data. The 'VncState' used in 'vnc_zrle_clear' is the connection
'VncState'. In currently implementation there will be a memory leak when the
vnc disconnect. Following is the asan output backtrack:

10 0xffffa53965cb in thread_start (/lib64/libc.so.6+0xd55cb)
This is because the opaque allocated in 'deflateInit2' is not freed in
'deflateEnd'. The reason is that the 'deflateEnd' calls 'deflateStateCheck'
and in the latter will check whether 's->strm != strm'(libz's data structure).
This check will be true so in 'deflateEnd' it just return 'Z_STREAM_ERROR' and
not free the data allocated in 'deflateInit2'.
The reason this happens is that the 'VncState' contains the whole 'VncZrle',
so when calling 'deflateInit2', the 's->strm' will be the local address.
So 's->strm != strm' will be true.
To fix this issue, we need to make 'zrle' of 'VncState' to be a pointer.
Then the connection 'VncState' and local 'VncState' exchange mechanism will
work as expection. The 'tight' of 'VncState' has the same issue, let's also turn
it to a pointer.

[/INST] 'cwe': ['CWE-401'], 'message': 'vnc: fix memory leak when vnc disconnect
Currently when qemu receives a vnc connect, it creates a 'VncState' to
represent this connection. In 'vnc_worker_thread_loop' it creates a
local 'VncState'. The connection 'VcnState' and local 'VncState' exchange
data in 'vnc_async_encoding_start' and 'vnc_async_encoding_end'.
In 'zrle_compress_data' it calls 'deflateInit2' to allocate the libz library
opaque data. The 'VncState' used in 'zrle_compress_data' is the local
'VncState'. In 'vnc_zrle_clear' it calls 'deflateEnd' to free the libz
library opaque data. The 'VncState' used in 'vnc_zrle_clear' is the connection
'VncState'. In currently implementation there will be a memory leak when the
vnc disconnect. Following is the asan output backtrack:
Direct leak of 29760 byte(s) in 5 object(s) allocated from:
0 0xffffa67ef3c3 in __interceptor_calloc (/lib64/libasan.so.4+0xd33c3)

10 0xffffa53965cb in thread_start (/lib64/libc.so.6+0xd55cb)
This is because the opaque allocated in 'deflateInit2' is not freed in
'deflateEnd'. The reason is that the 'deflateEnd' calls 'deflateStateCheck'
and in the latter will check whether 's->strm != strm'(libz's data structure).
This check will be true so in 'deflateEnd' it just return 'Z_STREAM_ERROR' and
not free the data allocated in 'deflateInit2'.
The reason this happens is that the 'VncState' contains the whole 'VncZrle',
so when calling 'deflateInit2', the 's->strm' will be the local address.
So 's->strm != strm' will be true.
To fix this issue, we need to make 'zrle' of 'VncState' to be a pointer.
Then the connection 'VncState' and local 'VncState' exchange mechanism will
work as expection. The 'tight' of 'VncState' has the same issue, let's also turn
it to a pointer.
