  • CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207189).
  • CVE-2023-31436: Fixed an out-of-bounds write in qfq_change_class() because lmax can exceed QFQ_MIN_LMAX (bsc#1210989).
