The Linux kernel before 3.12, when UDP Fragmentation Offload (UFO) is
enabled, does not properly initialize certain data structures, which
allows local users to cause a denial of service (memory corruption and
system crash) or possibly gain privileges via a crafted application
that uses the UDP_CORK option in a setsockopt system call and sends
both short and long packets, related to the ip_ufo_append_data
function in net/ipv4/ip_output.c and the ip6_ufo_append_data function
