CVE-2007-4573: The Anatomy of a Kernel Exploit - Made of Bugs
3.5 parsecs away

Travel
| | CVE-2007-4573 is two years old at this point, but it remains one of my favorite vulnerabilities. It was a local privilege-escalation vulnerability on all x86_64 kernels prior to v2.6.22.7. It's very simple to understand with a little bit of background, and the exploit is super-simple, but it's still more interesting than Yet Another NULL Pointer Dereference. Plus, it was the first kernel bug I wrote an exploit for, which was fun.
