CVE-2023-52644

6.3 · MEDIUM
Published Apr 17, 2024 linux EPSS 0.23% (14th pctl)

Overview

CVE-2023-52644 is a medium-severity vulnerability affecting linux linux_kernel. It was published on April 17, 2024 and has a CVSS 3.1 base score of 6.3 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.3, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: b43: Stop/wake correct queue in DMA Tx path when QoS is disabled

When QoS is disabled, the queue priority value will not map to the correct

ieee80211 queue since there is only one queue. Stop/wake queue 0 when QoS

is disabled to prevent trying to stop/wake a non-existent queue and failing

to stop/wake the actual queue instantiated.

Log of issue before change (with kernel parameter qos=0):
