Linux Kernel ath12k WMI Command Handling Vulnerability During Firmware Recovery

Vulnerability

A vulnerability in the Linux kernel's ath12k Wi-Fi driver allows WMI commands to be sent to the firmware during its recovery from a crash. This can lead to command failures and generate a kernel call trace indicating a problem. The issue arises because the host driver does not properly manage the timing of WMI command transmissions in relation to the firmware's recovery process.

Impact

The vulnerability can cause WMI command failures and disrupt normal driver-firmware communication, potentially leading to degraded performance or functionality of the Wi-Fi driver.
