CVE-2023-52644

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.8.1 (b43 component)

Description The vulnerability is related to the b43 component in the Linux kernel. It is caused by an incorrect mapping of the queue priority value to the correct ieee80211 queue when QoS is disabled, resulting in the stop/wake of a non-existent queue. This can lead to a denial-of-service (DoS) condition. The issue is resolved by stopping/waking queue 0 when QoS is disabled.

Recommendations To resolve the issue, upgrade the Linux kernel to version 6.8.1 or later. If an upgrade is not possible, consider disabling the b43 component or applying a patch to fix the issue. Additionally, monitor systems for suspicious activity on the local network and audit systems using affected versions.
