Vulnerability Name:

CVE-2006-2629 (CCN-26746)

Assigned:2006-05-26
Published:2006-05-26
Updated:2017-07-20
Summary:Race condition in Linux kernel 2.6.15 to 2.6.17, when running on SMP platforms, allows local users to cause a denial of service (crash) by creating and exiting a large number of tasks, then accessing the /proc entry of a task that is exiting, which causes memory corruption that leads to a failure in the prune_dcache function or a BUG_ON error in include/linux/list.h.
