CVE-2014-8086

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.18

Description A race condition exists in the ext4 file write iter function, allowing local users to cause a denial of service by making a file unavailable. This can be achieved through a combination of a write action and an F SETFL fcntl operation for the O DIRECT flag.

Recommendations For Linux kernel versions prior to 3.18, consider upgrading to version 3.18 or later to resolve the issue. As a temporary workaround, consider restricting the use of the O DIRECT flag to minimize the risk of exploitation.
