Publication date: 2026-05-08

Last updated on: 2026-05-08

Assigner: kernel.org

Description
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.

Executive Summary

This vulnerability exists in the Linux kernel's iwlwifi driver, specifically in the mvm component. It involves the handling of a command related to Wi-Fi 6E support called MCC_ALLOWED_AP_TYPE_CMD. The issue arises because the firmware incorrectly advertises support for this command even on devices like the AX201, which do not actually support Wi-Fi 6E. As a result, sending this unsupported command causes the firmware to crash.

Impact Analysis

The impact of this vulnerability is that the firmware on affected devices can crash when the unsupported 6E related command is sent. This can lead to device instability or loss of wireless connectivity, potentially disrupting network access on affected systems.
