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 received fragments be cleared from memory after (re)connecting to a network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP, CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
