CVE-2013-2141

Published: 04 June 2013

The do_tkill function in kernel/signal.c in the Linux kernel before 3.8.9 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via a crafted application that makes a (1) tkill or (2) tgkill system call.

From the Ubuntu security team

An information leak was discovered in the Linux kernel's tkill and tgkill system calls when used from compat processes. A local user could exploit this flaw to examine potentially sensitive kernel memory.
