Summary

Security update for the Linux Kernel

Details

The SUSE Linux Enterprise 12 SP3 kernel was updated 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-2022-1679: 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-2022-33981: Fixed use-after-free in floppy driver (bsc#1200692)
CVE-2022-20141: Fixed a possible use after free due to improper locking in ipcheckmc_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-2021-26341: Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage (bsc#1201050).
CVE-2017-16525: Fixed a use-after-free after failed setup in usb/serial/console (bsc#1066618).

The following non-security bugs were fixed:

exec: Force single empty string when argv is empty (bsc#1200571).
