**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 3.1.5 **Description** The issue is related to an integer overflow in the `drm mode dirtyfb ioctl` function, which can be exploited by local users to gain privileges or cause a denial of service due to memory corruption. This can be achieved via a crafted ioctl call. **Recommendations** For Linux kernel versions prior to 3.1.5, update to version 3.1.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the `drm mode dirtyfb ioctl` function to minimize the risk of exploitation.
