## AI overview

This article examines CVE-2010-3081, a Linux kernel vulnerability that enabled local privilege escalation on many 64-bit systems. It argues that commonly reported facts about the vulnerability were incorrect and that disabling 32-bit binaries did not fully prevent exploitation.

## Source excerpt

Most of you reading this blog probably remember CVE-2010-3081. The bug got an awful lot of publicity when it was discovered an announced, due to allowing local privilege escalation against virtually all 64-bit Linux kernels in common use at the time. While investigating CVE-2010-3081, I discovered that several of the commonly-believed facts about the CVE were wrong, and it was even more broadly exploitable than was publically documented. I'd like to share those observations here.
