SUSE: 2019:0326-1 important: the Linux Kernel (Live Patch 34 for SLE 12)
Summary
This update for the Linux Kernel 3.12.61-52_128 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).
