Summary: Security update for the Linux Kernel

Details: The SUSE Linux Enterprise 15 SP2 LTSS 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-2022-2663: 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-2022-3028: Fixed race condition that was found in the IP framework for transforming packets (XFRM subsystem) (bnc#1202898). - CVE-2020-27784: Fixed a vulnerability that was found in printer_ioctl() printer_ioctl() when accessing a deallocated instance (bnc#1202895). - CVE-2021-4155: Fixed a data leak flaw that was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem (bnc#1194272). - CVE-2022-2905: Fixed tnum_range usage on array range checking for poke descriptors (bsc#1202564, bsc#1202860). - CVE-2022-2977: Fixed reference counting for struct tpm_chip (bsc#1202672). - 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-2022-2588: Fixed use-after-free in cls_route (bsc#1202096). - 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-2022-36879: Fixed an issue in xfrm_expand_policies in net/xfrm/xfrm_policy.c where a refcount could be dropped twice (bnc#1201948). - CVE-2022-20368: 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-2022-26373: Fixed non-transparent sharing of return predictor targets between contexts in some Intel Processors (bnc#1201726). - CVE-2016-3695: Fixed an issue inside the einj_error_inject function in drivers/acpi/apei/einj.c that allowed users to simulate hardware errors and consequently cause a denial of service (bnc#1023051). - CVE-2022-2639: Fixed an integer coercion error that was found in the openvswitch kernel module (bnc#1202154). - 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-2022-32250: Fixed a privilege escalation issue in net/netfilter/nf_tables_api.c that allowed a local user to became root (bnc#1200015) - 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-2022-20166: Fixed possible out of bounds write due to a heap buffer overflow in various methods of kernel base drivers (bnc#1200598). The following non-security bugs were fixed: - cifs: fix uninitialized pointer in error case in dfs_cache_get_tgt_share (bsc#1188944). - cifs: skip trailing separators of prefix paths (bsc#1188944). - config: Update files NVRAM=y (bsc#1201361 bsc#1192968). - kernel-obs-build: include qemu_fw_cfg (boo#1201705) - lightnvm: Remove lightnvm implemenation (bsc#1191881 bsc#1201420 ZDI-CAN-17325). - md/bitmap: do not set sb values if can't pass sanity check (bsc#1197158). - mm/rmap: Fix anon_vma->degree ambiguity leading to double-reuse (git-fixes, bsc#1203098). - mm: pagewalk: Fix race between unmap and page walker (git-fixes, bsc#1203159). - net_sched: cls_route: disallow handle of 0 (bsc#1202393). - objtool: Add support for intra-function calls (bsc#1202396). - objtool: Make handle_insn_ops() unconditional (bsc#1202396). - objtool: Remove INSN_STACK (bsc#1202396). - objtool: Rework allocating stack_ops on decode (bsc#1202396). - objtool: Support multiple stack_op per instruction (bsc#1202396). - rpm: Fix parsing of rpm/macros.kernel-source on SLE12 (bsc#1201019). - tcp: add some entropy in __inet_hash_connect() (bsc#1180153). - tcp: change source port randomizarion at connect() time (bsc#1180153).
