Description

The XFS implementation in the Linux kernel before 3.15 improperly uses an old size value during remote attribute replacement, which allows local users to cause a denial of service (transaction overrun and data corruption) or possibly gain privileges by leveraging XFS filesystem access.

How to fix

Upgrade to a fixed version: Linux kernel 3.15. Check the vendor advisory for mitigations.
