The following security bugs were fixed:

- CVE-2021-4203: Fixed use-after-free read flaw that was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() (bnc#1194535).

- CVE-2022-2663: Fixed an issue that was found in nf_conntrack_irc where the message handling could be confused and incorrectly matches the message (bnc#1202097).
- CVE-2022-2977: Fixed reference counting for struct tpm_chip (bsc#1202672).
- CVE-2022-3028: Fixed race condition that was found in the IP framework for transforming packets (XFRM subsystem) (bnc#1202898).
- CVE-2022-36879: Fixed an issue in xfrm_expand_policies in net/xfrm/xfrm_policy.c where a refcount could be dropped twice (bnc#1201948).
- CVE-2022-39188: Fixed race condition in include/asm-generic/tlb.h where a device driver can free a page while it still has stale TLB entries (bnc#1203107).
