CVE-2023-23454

Name of the Vulnerable Software and Affected Versions Linux kernel versions through 6.1.4

Description The issue is related to the cbq classify function in the Linux kernel, which can cause a denial of service due to type confusion. This confusion occurs because non-negative numbers can sometimes indicate a TC ACT SHOT condition rather than valid classification results, leading to a slab-out-of-bounds read. The problem is associated with incorrect type determination in the packet prioritization subsystem.

Recommendations For Linux kernel versions through 6.1.4, update to a version that contains a fix for this issue to prevent exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
