Description Thierry Carrez (RETIRED) gentoo-dev

In latest Ubuntu's advisory

Vasiliy Averin discovered a Denial of Service vulnerability in the
"tiocgdev" ioctl call and in the "routing_ioctl" function. By calling
fget() and fput() in special ways, a local attacker could exploit this
to destroy file descriptor structures and crash the kernel.
