The SUSE Linux Enterprise 15 SP1 RT kernel was updated to receive various security and bug fixes.

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-2020-14351: 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).
