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.
