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).");
