CVE-2007-2875
First published: Mon Jun 11 2007(Updated: )
Integer underflow in the cpuset_tasks_read function in the Linux kernel before 2.6.20.13, and 2.6.21.x before 2.6.21.4, when the cpuset filesystem is mounted, allows local users to obtain kernel memory contents by using a large offset when reading the /dev/cpuset/tasks file.
