In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: Prevent sending WMI commands to firmware during firmware crash
Currently, we encounter the following kernel call trace when a firmware
crash occurs. This happens because the host sends WMI commands to the
firmware while it is in recovery, causing the commands to fail and
resulting in the kernel call trace.
Set the ATH12K_FLAG_CRASH_FLUSH and ATH12K_FLAG_RECOVERY flags when the
host driver receives the firmware crash notification from MHI. This
prevents sending WMI commands to the firmware during recovery.
Call Trace:
