drm/ast: astdp: Fix timeout for enabling video signal
The ASTDP transmitter sometimes takes up to 1 second for enabling the
video signal, while the timeout is only 200 msec. This results in a
kernel error message. Increase the timeout to 1 second. An example
of the error message is shown below.

This is a cosmetical problem. Enabling the video signal still works
even with the error message. The problem has always been present, but
only recent versions of the ast driver warn about missing the timeout. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: bail out when failed to load fw in psp_init_cap_microcode()
In function psp_init_cap_microcode(), it should bail out when failed to
load firmware, otherwise it may cause invalid memory access. |
| In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Validate the persistent meta data subbuf array
The meta data for a mapped ring buffer contains an array of indexes of all
the subbuffers. The first entry is the reader page, and the rest of the
entries lay out the order of the subbuffers in how the ring buffer link
list is to be created.
The validator currently makes sure that all the entries are within the
range of 0 and nr_subbufs. But it does not check if there are any
duplicates.
While working on the ring buffer, I corrupted this array, where I added
duplicates. The validator did not catch it and created the ring buffer
link list on top of it. Luckily, the corruption was only that the reader
page was also in the writer path and only presented corrupted data but did
not crash the kernel. But if there were duplicates in the writer side,
then it could corrupt the ring buffer link list and cause a crash.
Create a bitmask array with the size of the number of subbuffers. Then
clear it. When walking through the subbuf array checking to see if the
entries are within the range, test if its bit is already set in the
subbuf_mask. If it is, then there is duplicates and fail the validation.
If not, set the corresponding bit and continue. |
| In the Linux kernel, the following vulnerability has been resolved:
sched_ext: Fix incorrect autogroup migration detection
scx_move_task() is called from sched_move_task() and tells the BPF scheduler
that cgroup migration is being committed. sched_move_task() is used by both
cgroup and autogroup migrations and scx_move_task() tried to filter out
autogroup migrations by testing the destination cgroup and PF_EXITING but
this is not enough. In fact, without explicitly tagging the thread which is
doing the cgroup migration, there is no good way to tell apart
scx_move_task() invocations for racing migration to the root cgroup and an
autogroup migration.
This led to scx_move_task() incorrectly ignoring a migration from non-root
cgroup to an autogroup of the root cgroup triggering the following warning:
WARNING: CPU: 7 PID: 1 at kernel/sched/ext.c:3725 scx_cgroup_can_attach+0x196/0x340

Fix it by adding an argument to sched_move_task() that indicates whether the
moving is for a cgroup or autogroup migration. After the change,
scx_move_task() is called only for cgroup migrations and renamed to
scx_cgroup_move_task(). |
| In the Linux kernel, the following vulnerability has been resolved:
media: vimc: skip .s_stream() for stopped entities
Syzbot reported [1] a warning prompted by a check in call_s_stream()
that checks whether .s_stream() operation is warranted for unstarted
or stopped subdevs.
Add a simple fix in vimc_streamer_pipeline_terminate() ensuring that
entities skip a call to .s_stream() unless they have been previously
properly started.

| In the Linux kernel, the following vulnerability has been resolved:
mm: multi-gen LRU: fix crash during cgroup migration
lru_gen_migrate_mm() assumes lru_gen_add_mm() runs prior to itself. This
isn't true for the following scenario:
CPU 1 CPU 2
clone()
cgroup_can_fork()
cgroup_procs_write()
cgroup_post_fork()
task_lock()
lru_gen_migrate_mm()
task_unlock()
task_lock()
lru_gen_add_mm()
task_unlock()
And when the above happens, kernel crashes because of linked list
corruption (mm_struct->lru_gen.list). |
| In the Linux kernel, the following vulnerability has been resolved:
can: isotp: split tx timer into transmission and timeout
The timer for the transmission of isotp PDUs formerly had two functions:
1. send two consecutive frames with a given time gap
2. monitor the timeouts for flow control frames and the echo frames
This led to larger txstate checks and potentially to a problem discovered
by syzbot which enabled the panic_on_warn feature while testing.
The former 'txtimer' function is split into 'txfrtimer' and 'txtimer'
to handle the two above functionalities with separate timer callbacks.
The two simplified timers now run in one-shot mode and make the state
transitions (especially with isotp_rcv_echo) better understandable. |
| MeterSphere is an open source continuous testing platform. Prior to version 2.10.25-lts, a logic flaw allows retrieval of arbitrary user information. This allows an unauthenticated attacker to log in to the system as any user. This issue has been patched in version 2.10.25-lts. |
