NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_3_18-150200_24_139-default package and not the kernel-livepatch-5_3_18-150200_24_139-default package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

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