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 in net/ipv6/ip6_output.c.
