   An update that solves 16 vulnerabilities, contains 6
   features and has 29 fixes is now available.

Description:


   The SUSE Linux Enterprise 15 SP3 RT kernel was updated to receive various
   security and bugfixes.


   The following security bugs were fixed:

     (bnc#1198515).
   - CVE-2022-28893: Ensuring that sockets are in the intended state inside
     the SUNRPC subsystem (bnc#1198330).

     vgem_gem_dumb_create (bsc#1198742).
   - CVE-2022-1353: Fixed access controll to kernel memory in the
     pfkey_register function in net/key/af_key.c (bnc#1198516).
   - CVE-2022-1280: Fixed a use-after-free vulnerability in drm_lease_held in
     drivers/gpu/drm/drm_lease.c (bnc#1197914).

     kernel/cgroup/cgroup-v1.c. A local attacker with a user privilege could
     cause a privilege escalation by exploiting the fsconfig syscall
     parameter leading to a container breakout and a denial of service on the
     system (bnc#1193842).

     inside dma_buf_releas e of dma-buf.c (bnc#1198437).
   - CVE-2020-27835: Fixed use after free in infiniband hfi1 driver in the
     way user calls Ioctl after open dev file and fork. A local user could
     use this flaw to crash the system (bnc#1179878).
