## Overview

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: mvm: don't send a 6E related command when not supported

MCC_ALLOWED_AP_TYPE_CMD is related to 6E support. Do not send it if the
device doesn't support 6E.
Apparently, the firmware is mistakenly advertising support for this
command even on AX201 which does not support 6E and then the firmware
crashes.
