Race condition in the L2TPv3 IP Encapsulation feature in the Linux kernel
before 4.8.14 allows local users to gain privileges or cause a denial of
service (use-after-free) by making multiple bind system calls without
properly ascertaining whether a socket has the SOCK_ZAPPED status, related
to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c.
