CVE-2023-23455
First published: Thu Jan 12 2023(Updated: )
A denial of service flaw was found in atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel. In this flaw a local attacker may 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).
