Security update for the Linux Kernel
The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - 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). - 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 (bsc#1203098). - lightnvm: Removed lightnvm implemenation (bsc#1191881).
