** Description changed: - [vfs: refcount issues during unmount on symlink] + The mountpoint_last function in fs/namei.c in the Linux kernel before + 3.15.8 does not properly maintain a certain reference count during + attempts to use the umount system call in conjunction with a symlink, + which allows local users to cause a denial of service (memory + consumption or use-after-free) or possibly have unspecified other impact + via the umount program.
