CVE-2023-23454  (opens in a new tab)
CWE-843  (opens in a new tab)

How to fix?

Upgrade SLES:15.1 kernel-syms to version 4.12.14-150100.197.142.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-syms package and not the kernel-syms package as distributed by SLES. See How to fix? for SLES:15.1 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).
