  • CVE-2022-2585: Fixed use-after-free in POSIX CPU timer (bsc#1202163).
  • CVE-2022-36946: Fixed a remote denial of service attack inside nfqnl_mangle in net/netfilter/nfnetlink_queue.c, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative length (bsc#1201941).

Описание

nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encounter a negative skb->len.
