CVE-2011-1745

Published: 09 May 2011

Integer overflow in the agp_generic_insert_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 allows local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_BIND agp_ioctl ioctl call.

From the Ubuntu security team

Vasiliy Kulikov discovered that the AGP driver did not check certain ioctl values. A local attacker with access to the video subsystem could exploit this to crash the system, leading to a denial of service, or possibly gain root privileges.
