Linux Kernel UFO Memory Corruption Privilege Escalation Exploit

This module exploits a memory corruption vulnerability in the Linux kernel. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption that can be used by an attacker to escalate privileges.
