Security update for the Linux Kernel (Live Patch 0 for SLE 15)

This update for the Linux Kernel 4.12.14-23 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 can 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).
