CVE-2022-49539

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A vulnerability in the Linux kernel has been resolved, specifically in the rtw89 module. The issue involves CAM leaks during the L2 reset process and ieee80211 restart hw() function call. The CAM, which refers to address CAM and bssid CAM, would leak during this process. The normal flow of the system would result in leaks after L2 reset if a non-sec connection is present. The ieee80211 restart hw() flow would also cause additional leaks. The fix involves releasing CAM before HW restart, regardless of the connection type, and checking if CAM is already valid to avoid multiple acquisitions.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
