FYI I saw a real life attempt to exploit this over the weekend on a
machine of mine where someone had found a PHP exploit. Fortunately, I
had already upgraded the kernel and their rootkit attempt failed,
however it's worth emphasizing that this is certainly out there.

I have more information on the rootkit they used for legitimate security
researchers who are interested in the issue.
