AI-suggested
A patch is available for this vulnerability and should be applied. The fix prevents sending the 6E related command when the device does not support it, thereby avoiding firmware crashes. Users should update to linux-hwe-edge kernel version 7.0.0-1006.6 or later.
Description
A vulnerability in the Linux kernel's iwlwifi driver was fixed to prevent sending a 6E related command (MCC_ALLOWED_AP_TYPE_CMD) when the device does not support 6E. The issue arises because the firmware incorrectly advertises support for this command on devices like AX201 that do not actually support 6E, causing the firmware to crash. This vulnerability affects multiple versions of the linux-hwe-edge kernel and has a medium severity rating with a CVSS score of 5.5.
