Security Advisory Description
A flaw was found in the Linux kernel’s NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can 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. (CVE-2018-16884)
Impact
There is no impact; F5 products are not affected by this vulnerability.
