______________________________________________________________________________

   An update that solves 5 vulnerabilities and has two fixes
   is now available.

Description:


   The SUSE Linux Enterprise 15 kernel was updated.

   The following security bugs were fixed:

   - CVE-2022-3303: Fixed a race condition in the sound subsystem due to
     improper locking (bnc#1203769).
   - CVE-2022-41218: Fixed an use-after-free caused by refcount races in
     drivers/media/dvb-core/dmxdev.c (bnc#1202960).
   - CVE-2022-3239: Fixed an use-after-free in the video4linux driver that
     could lead a local user to able to crash the system or escalate their
     privileges (bnc#1203552).
   - CVE-2022-41848: Fixed a race condition and resultant use-after-free if a
     physically proximate attacker removes a PCMCIA device while calling
     ioctl (bnc#1203987).
   - CVE-2022-2503: Fixed a bug in dm-verity, device-mapper table reloads
     allowed users with root privileges to switch out the target with an
     equivalent dm-linear target and bypass verification till reboot. This
     allowed root to bypass LoadPin and can be used to load untrusted and
     unverified kernel modules and firmware, which implies arbitrary kernel
     execution and persistence for peripherals that do not verify firmware
     updates (bnc#1202677).

   The following non-security bugs were fixed:

   - dtb: Do not include sources in src.rpm - refer to kernel-source Same as
     other kernel binary packages there is no need to carry duplicate sources
     in dtb packages.
   - net: mana: Add rmb after checking owner bits (git-fixes).
   - net: mana: Add the Linux MANA PF driver (bug#1201309, jsc#PED-529).
   - x86/bugs: Reenable retbleed=off While for older kernels the return
     thunks are statically built in and cannot be dynamically patched out,
     retbleed=off should still be possible to do so that the mitigation can
     still be disabled on Intel who do not use the return thunks but IBRS.


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-15-2022-3688=1

   - SUSE Linux Enterprise Server 15-LTSS:

      zypper in -t patch SUSE-SLE-Product-SLES-15-2022-3688=1

   - SUSE Linux Enterprise Module for Live Patching 15:

      zypper in -t patch SUSE-SLE-Module-Live-Patching-15-2022-3688=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:

      zypper in -t patch SUSE-SLE-Product-HPC-15-2022-3688=1

   - SUSE Linux Enterprise High Performance Computing 15-ESPOS:

      zypper in -t patch SUSE-SLE-Product-HPC-15-2022-3688=1

   - SUSE Linux Enterprise High Availability 15:

      zypper in -t patch SUSE-SLE-Product-HA-15-2022-3688=1
