NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150400_15_11-rt package and not the kernel-livepatch-5_14_21-150400_15_11-rt package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results).
