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.
