CVE-2025-38291 — wifi: ath12k: Prevent sending WMI commands to firmware during firmware crash

Affected: Linux

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.
