CVE-2006-0744  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 2.6.16.5 or higher.

Overview

Affected versions of this package are vulnerable to Improper Input Validation. Linux kernel before 2.6.16.5 does not properly handle uncanonical return addresses on Intel EM64T CPUs, which reports an exception in the SYSRET instead of the next instruction, which causes the kernel exception handler to run on the user stack with the wrong GS.
