The SUSE Linux Enterprise 15 SP3 RT kernel was updated to 3.12.31 to receive various security and bugfixes.
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-2022-34918: Fixed a buffer overflow with nftsetelem_init() that could be used by a local attacker to escalate privileges (bnc#1201171).
CVE-2021-26341: Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage (bsc#1201050).
CVE-2022-1679: Fixed a use-after-free in the Atheros wireless driver in the way a user forces the ath9khtcwaitfortarget 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-2022-1012: Fixed information leak caused by small table perturb size in the TCP source port generation algorithm (bsc#1199482).
CVE-2022-33981: Fixed use-after-free in floppy driver (bsc#1200692)
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 locksocknested of sock.c. This could lead to local escalation of privilege with System execution privileges needed (bsc#1200599).
The following non-security bugs were fixed:
Add missing recommends of kernel-install-tools to kernel-source-vanilla (bsc#1200442)
