In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name
is not called before register_netdevice. This allows local users to cause a
denial of service (NULL pointer dereference and panic) via an
ioctl(TUNSETIFF) call with a dev name containing a / character. This is
similar to CVE-2013-4343.
