The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security
and bugfixes.
The following security bugs were fixed:
o 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).
o 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).
o 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).
o CVE-2022-33981: Fixed use-after-free in floppy driver (bsc#1200692)

ip_check_mc_rcu() (bsc#1200604).
o 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).
o CVE-2021-26341: Some AMD CPUs may transiently execute beyond unconditional
direct branches, which may potentially result in data leakage (bsc#
1201050).
o CVE-2017-16525: Fixed a use-after-free after failed setup in usb/serial/
console (bsc#1066618).
