  "description": "\r\n\r\nSecurity Fix(es):\r\n\r\nst21nfca_connectivity_event_received in drivers/nfc/st21nfca/se.c in the Linux kernel through 5.16.12 has EVT_TRANSACTION buffer overflows because of untrusted length parameters.(CVE-2022-26490)\r\n\r\nThe Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges.(CVE-2022-36123)\n\nA use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the Linux kernel. This flaw allows a local, privileged attacker to crash the system, possibly leading to a local privilege escalation issue.(CVE-2022-2588)\n\nIt was discovered that when exec ing from a non-leader thread, armed POSIX CPU timers would be left on a list but freed, leading to a use-after-free.(CVE-2022-2585)",
