Description

A flaw was found in the Linux kernel's Intel i915 graphics driver. A local user could exploit this vulnerability to cause a Denial of Service (DoS) or potentially gain elevated privileges. By submitting a crafted graphics execution request that triggers an error path during relocation handling, an attacker causes the driver to free memory beyond the allocated array boundaries. This improper memory release results in kernel memory corruption and a system crash.
