  <description>
The SUSE Linux Enterprise 15 SP1 LTSS kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2020-36516: Fixed an issue in the mixed IPID assignment method where an attacker was able to inject data into or terminate a victim's TCP session (bnc#1196616).
- 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-2022-1012: Fixed a memory leak problem that was found in the TCP source port generation algorithm in net/ipv4/tcp.c (bnc#1199482).
- CVE-2022-20368: Fixed slab-out-of-bounds access in packet_recvmsg() (bsc#1202346).
- CVE-2022-20369: Fixed out of bounds write in v4l2_m2m_querybuf of v4l2-mem2mem.c (bnc#1202347).
- CVE-2022-21385: Fixed a flaw in net_rds_alloc_sgs() that allowed unprivileged local users to crash the machine (bnc#1202897).
- CVE-2022-2588: Fixed use-after-free in cls_route (bsc#1202096).
- CVE-2022-26373: Fixed non-transparent sharing of return predictor targets between contexts in some Intel Processors (bnc#1201726).
- CVE-2022-2639: Fixed an integer coercion error that was found in the openvswitch kernel module (bnc#1202154).
- 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-2022-29581: Fixed improper update of reference count vulnerability in net/sched that allowed a local attacker to cause privilege escalation to root (bnc#1199665).
- 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).

The following non-security bugs were fixed:
