CVE-2012-3375

Published: 04 July 2012

The epoll_ctl system call in fs/eventpoll.c in the Linux kernel before 3.2.24 does not properly handle ELOOP errors in EPOLL_CTL_ADD operations, which allows local users to cause a denial of service (file-descriptor consumption and system crash) via a crafted application that attempts to create a circular epoll dependency. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-1083.

From the Ubuntu security team

A flaw was discovered in the Linux kernel's epoll system call. An unprivileged local user could use this flaw to crash the system.
