A flaw was found in the Linux kernel's implementation of raw_sendmsg allowing a local attacker to panic the kernel or possibly leak kernel addresses. A local attacker, with the privilege of creating raw sockets, can abuse a possible race condition when setting the socket option to allow the kernel to automatically create ip header values and thus potentially escalate their privileges.
