CVE-2015-4177

The collectmounts function in fs/namespace.c in the Linux kernel before 4.0.5 does not properly consider that it may execute after a path has been unmounted, which allows local users to cause a denial of service system crash by leveraging user-namespace root access for an MNTDETACH umount2 system...
