   An update that solves 15 vulnerabilities and has one errata
   is now available.

Description:

   The SUSE Linux Enterprise 15 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-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-2022-2318: Fixed a use-after-free vulnerabilities in the timer
     handler in net/rose/rose_timer.c that allow attackers to crash the
     system without any privileges (bsc#1201251).
   - CVE-2022-26365, CVE-2022-33740, CVE-2022-33741, CVE-2022-33742: Fixed
     multiple potential data leaks with Block and Network devices when using
     untrusted backends (bsc#1200762).
   - CVE-2021-26341: Some AMD CPUs may transiently execute beyond
     unconditional direct branches, which may potentially result in data
     leakage (bsc#1201050).
   - CVE-2020-26541: Enforce the secure boot forbidden signature database
     (aka dbx) protection mechanism. (bsc#1177282)

   The following non-security bugs were fixed:

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


Special Instructions and Notes:

   Please reboot the system after installing this update.

Patch Instructions:

   To install this SUSE Security Update use the SUSE recommended installation methods
   like YaST online_update or "zypper patch".

   Alternatively you can run the command listed for your product:

   - SUSE Linux Enterprise Server for SAP 15:

      zypper in -t patch SUSE-SLE-Product-SLES_SAP-15-2022-2407=1

   - SUSE Linux Enterprise Server 15-LTSS:

      zypper in -t patch SUSE-SLE-Product-SLES-15-2022-2407=1

   - SUSE Linux Enterprise Module for Live Patching 15:

      zypper in -t patch SUSE-SLE-Module-Live-Patching-15-2022-2407=1

      Please note that this is the initial kernel livepatch without fixes
      itself, this livepatch package is later updated by seperate standalone
      livepatch updates.   - SUSE Linux Enterprise High Performance Computing 15-LTSS:
