gpp_maybe Security update for the linux kernel
SUSE-SLE-Module-Live-Patching-15-SP2-2022-2423

The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security and bugfixes. NOTE: This update was retracted due to regressions with the RETBLEED security fixes on Intel x86. The following security bugs were fixed: - 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-2022-1679: 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-2022-20132: Fixed out of bounds read due to improper input validation in lg_probe and related functions of hid-lg.c (bsc#1200619). - CVE-2022-33981: Fixed use-after-free in floppy driver (bsc#1200692) - CVE-2022-20141: Fixed a possible use after free due to improper locking in ip_check_mc_rcu() (bsc#1200604). - 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-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-2021-26341: Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage (bsc#1201050). 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). - exec: Force single empty string when argv is empty (bsc#1200571). - vmxnet3: fix minimum vectors alloc issue (bsc#1199489).
