Upgrade Debian:12 firmware-nonfree to version 20210818-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream firmware-nonfree package and not the firmware-nonfree package as distributed by Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets.
