     (bnc#1203107).
   - 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-2022-3028: Fixed race condition that was found in the IP framework
     for transforming packets (XFRM subsystem) (bnc#1202898).
   - CVE-2022-2991: Fixed an heap-based overflow in the lightnvm
     implemenation (bsc#1201420).
   - CVE-2022-26373: Fixed non-transparent sharing of return predictor
     targets between contexts in some Intel Processors (bnc#1201726).
   - CVE-2022-2588: Fixed use-after-free in cls_route (bsc#1202096).
   - CVE-2022-21385: Fixed a flaw in net_rds_alloc_sgs() that allowed
     unprivileged local users to crash the machine (bnc#1202897).
   - CVE-2022-20369: Fixed out of bounds write in v4l2_m2m_querybuf of
     v4l2-mem2mem.c (bnc#1202347).
   - CVE-2022-20368: Fixed slab-out-of-bounds access in packet_recvmsg()
     (bsc#1202346).
   - 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-2019-3900: Fixed infinite loop the vhost_net kernel module that
     could result in a DoS scenario (bnc#1133374).

   The following non-security bugs were fixed:

   - net_sched: cls_route: Disallowed handle of 0 (bsc#1202393).
   - mm, rmap: Fixed anon_vma->degree ambiguity leading to double-reuse
