Linux kernel built with the name spaces support(CONFIG_NAMESPACE) is vulnerable to a potential privilege escalation flaw. It could occur when a process within a container escapes the intended bind mounts to access the full file system. A privileged user inside a container could use this flaw to potentially gain full privileges on a system.
