Affected Products:
                    SUSE Linux Enterprise Module for Realtime 15-SP2

   An update that solves 11 vulnerabilities and has 62 fixes
   is now available.


   The SUSE Linux Enterprise 15 SP2 RT kernel was updated to receive various
   security and bugfixes.

   The following security bugs were fixed:

   - CVE-2020-15436: Fixed a use after free vulnerability in fs/block_dev.c
     which could have allowed local users to gain privileges or cause a
     denial of service (bsc#1179141).
   - CVE-2020-15437: Fixed a null pointer dereference which could have
     allowed local users to cause a denial of service(bsc#1179140).
   - CVE-2020-25669: Fixed a use-after-free read in sunkbd_reinit()
   - CVE-2020-25705: Fixed A flaw in the way reply ICMP packets are limited
     in was found that allowed to quickly scan open UDP ports. This flaw
     allowed an off-path remote user to effectively bypassing source port UDP
     randomization. The highest threat from this vulnerability is to
     confidentiality and possibly integrity, because software and services
     that rely on UDP source port randomization (like DNS) are indirectly
     affected as well. Kernel versions may be vulnerable to this issue
     (bsc#1175721, bsc#1178782).
   - CVE-2020-27777: Restrict RTAS requests from userspace  (bsc#1179107)

     snd_rawmidi_kernel_read1() (bsc#1179601).
   - CVE-2020-28915: Fixed a buffer over-read in the fbcon code which could
     have been used by local attackers to read kernel memory (bsc#1178886).
   - CVE-2020-28941: Fixed an issue where local attackers on systems with the
     speakup driver could cause a local denial of service attack
   - CVE-2020-29369: Fixed a race condition between certain expand functions
     (expand_downwards and expand_upwards) and page-table free operations
     from an munmap call, aka CID-246c320a8cfe (bnc#1173504 bsc#1179432).
   - CVE-2020-29371: Fixed uninitialized memory leaks to userspace
   - CVE-2020-4788: Fixed an issue with IBM Power9 processors could have
     allowed a local user to obtain sensitive information from the data in
     the L1 cache under extenuating circumstances (bsc#1177666).
