Security update for the Linux Kernel (Live Patch 35 for SLE 12) SUSE Patch security@suse.de SUSE Security Team SUSE-SU-2019:0326-1 Final 1 1 2019-02-11T15:15:44Z current 2019-02-11T15:15:44Z 2019-02-11T15:15:44Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for the Linux Kernel (Live Patch 35 for SLE 12) This update for the Linux Kernel 3.12.61-52_133 fixes one issue. The following security issue was fixed: - CVE-2018-16884: A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time could make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user could cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out (bsc#1119947).
