Security update for the Linux Kernel (Live Patch 1 for SLE 15 SP4)

This update for the Linux Kernel 5.14.21-150400_24_11 fixes several issues.

The following security issues were fixed:

  • CVE-2020-36516: Fixed an off-path attack via mixed IPID assignment method with the hash-based IPID assignment policy to inject data into a victim's TCP session or terminate that session (bsc#1196867).
  • CVE-2021-39698: Fixed possible memory corruption in aio_poll_complete_work of aio.c, that could have led to local escalation of privilege with no additional execution privileges needed (bsc#1196959).
  • 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).

In aio_poll_complete_work of aio.c, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed.

Описание

It 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.

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.
