Description

Security update for the Linux Kernel The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2020-36557: Fixed a race condition between the VT_DISALLOCATE ioctl and closing/opening of ttys could lead to a use-after-free (bnc#1201429). - CVE-2020-36558: Fixed a race condition involving VT_RESIZEX which could lead to a NULL pointer dereference and general protection fault (bnc#1200910). - CVE-2021-4157: Fixed an out of memory bounds write flaw in the NFS subsystem, related to the replication of files with NFS. A user could potentially crash the system or escalate privileges on the system (bsc#1194013). - CVE-2021-26341: Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage (bsc#1201050). - CVE-2021-33655: Fixed memory out of bounds write by ioctl cmd FBIOPUT_VSCREENINFO (bnc#1201635). - CVE-2021-33656: Fixed memory out of bounds write related to ioctl cmd PIO_FONT (bnc#1201636). - CVE-2022-1116: Fixed a integer overflow vulnerability in io_uring which allowed a local attacker to cause memory corruption and escalate privileges to root (bnc#1199647). - CVE-2022-1462: Fixed an out-of-bounds read flaw in the TeleTYpe subsystem. This flaw allowed a local user to crash the system or read unauthorized random data from memory. (bnc#1198829) - CVE-2022-1679: Fixed a use-after-free in the Atheros wireless driver in the way a user forces the ath9k_htc_wait_for_target function to fail with some input messages (bsc#1199487). - CVE-2022-2318: Fixed a use-after-free vulnerabilities in the timer handler in net/rose/rose_timer.c that allow attackers to crash the system without any privileges (bsc#1201251). - CVE-2022-20132: Fixed out of bounds read due to improper input validation in lg_probe and related functions of hid-lg.c (bsc#1200619). - CVE-2022-20141: Fixed a possible use after free due to improper locking in ip_check_mc_rcu() (bsc#1200604). - CVE-2022-20154: Fixed a use after free due to a race condition in lock_sock_nested of sock.c. This could lead to local escalation of privilege with System execution privileges needed (bsc#1200599). - CVE-2022-21505: Fixed kexec lockdown bypass with ima policy (bsc#1201458). - CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742: Fixed multiple potential data leaks with Block and Network devices when using untrusted backends (bsc#1200762). - CVE-2022-29900, CVE-2022-29901: Fixed the RETBLEED attack, a new Spectre like Branch Target Buffer attack, that can leak arbitrary kernel information (bsc#1199657). - CVE-2022-33981: Fixed use-after-free in floppy driver (bsc#1200692) - CVE-2022-36946: Fixed incorrect packet truncation in nfqnl_mangle() that could lead to remote DoS (bnc#1201940). The following non-security bugs were fixed: - bcache: avoid unnecessary soft lockup in kworker update_writeback_rate() (bsc#1197362). - blk-mq: Fix wrong wakeup batch configuration which will cause hang (bsc#1200263). - blk-mq: clear active_queues before clearing BLK_MQ_F_TAG_QUEUE_SHARED (bsc#1200263). - blk-mq: fix tag_get wait task can't be awakened (bsc#1200263). - dma-direct: Fix potential NULL pointer dereference (bsc#1196472 ltc#192278). - dma-mapping: Allow mixing bypass and mapped DMA operation (bsc#1196472 ltc#192278). - dma-mapping: add a dma_ops_bypass flag to struct device (bsc#1196472 ltc#192278). - dma-mapping: move the remaining DMA API calls out of line (bsc#1196472 ltc#192278). - dma: kABI: Add back removed exports (bsc#1196472 ltc#192278). - exec: Force single empty string when argv is empty (bsc#1200571). - fsnotify: invalidate dcache before IN_DELETE event (bsc#1195478 bsc#1200905). - kvm: emulate: Fix SETcc emulation function offsets with SLS (bsc#1201930). - kvm: emulate: do not adjust size of fastop and setcc subroutines (bsc#1201930). - powerpc/dma: Fallback to dma_ops when persistent memory present (bsc#1196472 ltc#192278). - powerpc/pseries/iommu: Create defines for operations in ibm, ddw-applicable (bsc#1196472 ltc#192278). - powerpc/pseries/iommu: Fix window size for direct mapping with pmem (bsc#1196472 ltc#192278). - powerpc/pseries/iommu: Update call to ibm, query-pe-dma-windows (bsc#1196472 ltc#192278). - powerpc: dma: kABI workaround for moving around dma_bypass bit (bsc#1196472 ltc#192278). - powerpc: use the generic dma_ops_bypass mode (bsc#1196472 ltc#192278). - vmxnet3: fix minimum vectors alloc issue (bsc#1199489). - x86/bugs: Remove apostrophe typo (bsc#1114648). - x86/entry: Remove skip_r11rcx (bsc#1201644).
