______________________________________________________________________________

   An update that solves 11 vulnerabilities and has 74 fixes
   is now available.

Description:

   The SUSE Linux Enterprise 12 SP5 realtime kernel was updated to receive
   various security and bugfixes.


   The following security bugs were fixed:

   - CVE-2020-25705: 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-2020-8694: Insufficient access control for some Intel(R) Processors     may have allowed an authenticated user to potentially enable information
     disclosure via local access (bsc#1170415).
   - CVE-2020-25668: Fixed a use-after-free in con_font_op() (bsc#1178123).
   - CVE-2020-25656: Fixed a concurrency use-after-free in vt_do_kdgkb_ioctl
     (bnc#1177766).
   - CVE-2020-25285: Fixed a race condition between hugetlb sysctl handlers     in mm/hugetlb.c (bnc#1176485).
   - CVE-2020-0430: Fixed an OOB read in skb_headlen of
     /include/linux/skbuff.h (bnc#1176723).
   - CVE-2020-14351: Fixed a race in the perf_mmap_close() function
     (bsc#1177086).
   - CVE-2020-16120: Fixed permission check to open real file when using
     overlayfs. It was possible to have a file not readable by an
     unprivileged user be copied to a mountpoint controlled by that user and
     then be able to access the file (bsc#1177470).
   - CVE-2020-12351: Fixed a type confusion while processing AMP packets aka
     "BleedingTooth" aka "BadKarma" (bsc#1177724).
   - CVE-2020-12352: Fixed an information leak when processing certain AMP
     packets aka "BleedingTooth" (bsc#1177725).
