## AI overview

The article reviews several high-profile Linux privilege-escalation vulnerabilities from recent years, including CVE-2010-3081 and CVE-2010-3301, and notes that some flaws persisted across older kernel versions. It argues that the sample does not clearly show Linux becoming more secure over time.

## Source excerpt

After the fuss of the last two weeks because of CVE-2010-3081 and CVE-2010-3301, I decided to take a look at a handful of the high-profile privilege escalation vulnerabilities in Linux from the last few years. So, here's a summary of the ones I picked out. There are also a large number of smaller ones, like an AF\_CAN exploit, or the l2cap overflow in the Bluetooth subsystem, that didn't get as much publicity, because they were found more quickly or didn't affect as many default configurations.
