Other sources

Linux kernel built with an Ethernet driver(ex virtio-net) which has UDP Fragmentation Offload(UFO) feature ON is vulnerable to a memory corruption flaw when UDPCORK socket option is set. It could occur when sending large messages, wherein not all messages are greater than maximum transfer unit(MTU) of the underlying medium.

An unprivileged user/program could use this flaw to crash the kernel resulting in DoS, or potentially escalate their privileges on the system.

Upstream fix: ------------- -> http://patchwork.ozlabs.org/patch/285292/ -> https://git.kernel.org/linus/c547dbf55d5f8cf615ccc0e7265e98db27d3fb8b -> https://git.kernel.org/linus/e93b7d748be887cd7639b113ba7d7ef792a7efb9

— Red Hat

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 UDPCORK option in a setsockopt system call and sends both short and long packets, related to the ipufoappenddata function in net/ipv4/ipoutput.c and the ip6ufoappenddata function in net/ipv6/ip6output.c.
