CWE-20  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 2.6.39 or higher.

Overview

Affected versions of this package are vulnerable to Improper Input Validation. The do_task_stat function in fs/proc/array.c in the Linux kernel before 2.6.39-rc1 does not perform an expected uid check, which makes it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE binary.
