Vulnerability details
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to improper feature support validation in the iwlwifi mvm subsystem when handling 6E-related commands. A local user can trigger use of an unsupported MCC_ALLOWED_AP_TYPE_CMD path to cause a denial of service.
The issue occurs because some firmware incorrectly advertises support for the command on AX201 devices that do not support 6E, which can lead to a firmware crash.
