Security Vulnerabilities - CVEs Published In February 2025
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/pm: fix double free in si_parse_power_table()
In function si_parse_power_table(), array adev->pm.dpm.ps and its member
is allocated. If the allocation of each member fails, the array itself
is freed and returned with an error code. However, the array is later
freed again in si_dpm_fini() function which is called when the function
returns an error.
This leads to potential double free of the array adev->pm.dpm.ps, as
well as leak of its array members, since the members are not freed in
the allocation function and the array is not nulled when freed.
In addition adev->pm.dpm.num_ps, which keeps track of the allocated
array member, is not updated until the member allocation is
successfully finished, this could also lead to either use after free,
or uninitialized variable access in si_dpm_fini().
Fix this by postponing the free of the array until si_dpm_fini() and
increment adev->pm.dpm.num_ps everytime the array member is allocated.

In the Linux kernel, the following vulnerability has been resolved:
arm64: compat: Do not treat syscall number as ESR_ELx for a bad syscall
If a compat process tries to execute an unknown system call above the
__ARM_NR_COMPAT_END number, the kernel sends a SIGILL signal to the
offending process. Information about the error is printed to dmesg in
compat_arm_syscall() -> arm64_notify_die() -> arm64_force_sig_fault() ->
arm64_show_signal().
arm64_show_signal() interprets a non-zero value for
current->thread.fault_code as an exception syndrome and displays the
message associated with the ESR_ELx.EC field (bits 31:26).
current->thread.fault_code is set in compat_arm_syscall() ->
arm64_notify_die() with the bad syscall number instead of a valid ESR_ELx
value. This means that the ESR_ELx.EC field has the value that the user set
for the syscall number and the kernel can end up printing bogus exception
messages*. For example, for the syscall number 0x68000000, which evaluates
to ESR_ELx.EC value of 0x1A (ESR_ELx_EC_FPAC) the kernel prints this error:
[ 18.349161] syscall[300]: unhandled exception: ERET/ERETAA/ERETAB, ESR 0x68000000, Oops - bad compat syscall(2) in syscall[10000+50000]
[ 18.350639] CPU: 2 PID: 300 Comm: syscall Not tainted 5.18.0-rc1 #79
[ 18.351249] Hardware name: Pine64 RockPro64 v2.0 (DT)
[..]
which is misleading, as the bad compat syscall has nothing to do with
pointer authentication.
Stop arm64_show_signal() from printing exception syndrome information by
having compat_arm_syscall() set the ESR_ELx value to 0, as it has no
meaning for an invalid system call number. The example above now becomes:
[ 19.935275] syscall[301]: unhandled exception: Oops - bad compat syscall(2) in syscall[10000+50000]
[ 19.936124] CPU: 1 PID: 301 Comm: syscall Not tainted 5.18.0-rc1-00005-g7e08006d4102 #80
[ 19.936894] Hardware name: Pine64 RockPro64 v2.0 (DT)
[..]
which although shows less information because the syscall number,
wrongfully advertised as the ESR value, is missing, it is better than
showing plainly wrong information. The syscall number can be easily
obtained with strace.
*A 32-bit value above or equal to 0x8000_0000 is interpreted as a negative
integer in compat_arm_syscal() and the condition scno < __ARM_NR_COMPAT_END
evaluates to true; the syscall will exit to userspace in this case with the
ENOSYS error code instead of arm64_notify_die() being called.

In the Linux kernel, the following vulnerability has been resolved:
media: venus: hfi: avoid null dereference in deinit
If venus_probe fails at pm_runtime_put_sync the error handling first
calls hfi_destroy and afterwards hfi_core_deinit. As hfi_destroy sets
core->ops to NULL, hfi_core_deinit cannot call the core_deinit function
anymore.
Avoid this null pointer derefence by skipping the call when necessary.

The Oops happens because the I2C client data does not point to

max9286_init() which calls v4l2_i2c_subdev_init() later on...
Besides fixing the max9286_remove() function, remove the call to
i2c_set_clientdata() in max9286_probe(), to avoid confusion, and make
the necessary changes to max9286_init() so that it doesn't have to use
i2c_get_clientdata() in order to fetch the pointer to priv.
