The cumulative Virtuozzo ReadyKernel patch was updated with a security fix. The patch applies to all supported Virtuozzo kernels.
Vulnerability id: CVE-2018-16884
A flaw was found in the implementation of NFS v4.1 in the Linux kernel. NFS v4.1 shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel ID and cause a use-after-free. A malicious user in a container can exploit this to cause a host kernel memory corruption and a system crash.
