CVE-2023-23454: Debian Linux
Medium severity, CVSS 5.5. EPSS: 0.3% chance of exploitation in the next 30 days.
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).
