CVE-2012-6546

Published: 07 March 2013

The ATM implementation in the Linux kernel before 3.6 does not initialize certain structures, which allows local users to obtain sensitive information from kernel stack memory via a crafted application.

From the Ubuntu security team

Mathias Krause discovered information leaks in the Linux kernel's Asynchronous Transfer Mode (ATM) networking stack. A local user could exploit these flaws to examine some parts of kernel memory.
