Security update for the Linux Kernel (Live Patch 20 for SLE 15 SP1) SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2021:4038-1 Final 1 1 2021-12-14T08:22:33Z current 2021-12-14T08:22:33Z 2021-12-14T08:22:33Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for the Linux Kernel (Live Patch 20 for SLE 15 SP1) This update for the Linux Kernel 4.12.14-197_75 fixes several issues. The following security issues were fixed: - CVE-2021-0941: In bpf_skb_change_head of filter.c, there is a possible out of bounds read due to a use after free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1192045). - CVE-2021-20322: Make the ipv4 and ipv6 ICMP exception caches less predictive to avoid information leaks about UDP ports in use.

This flaw allows an off-path remote user to effectively bypass the 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.
