CVE-2011-1479

Published: 6 October 2011

Double free vulnerability in the inotify subsystem in the Linux kernel before 2.6.39 allows local users to cause a denial of service (system crash) via vectors involving failed attempts to create files. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-4250.

From the Ubuntu Security Team

It was discovered that the security fix for CVE-2010-4250 introduced a regression. A remote attacker could exploit this to crash the system, leading to a denial of service.
