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).
