The openSUSE Leap 15.1 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

  - CVE-2020-28915: A buffer over-read (at the framebuffer     layer) in the fbcon code could be used by local     attackers to read kernel memory, aka CID-6735b4632def     (bnc#1178886).

  - CVE-2020-25669: A use-after-free in teardown paths of     sunkbd was fixed (bsc#1178182).

  - CVE-2020-25705: A flaw in the way reply ICMP packets are     limited in the Linux kernel functionality 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 that relies on UDP source     port randomization are indirectly affected as well.
    Kernel versions may be vulnerable to this issue     (bnc#1175721 bnc#1178782).

  - CVE-2020-25704: A a memory leak in     perf_event_parse_addr_filter() was foxed (bsc#1178393,     CVE-2020-25704).
