An update that solves 9 vulnerabilities and has four fixes
is now available.
Description:
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 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-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).
