CVE-2011-1747

Publication date 9 May 2011

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The agp subsystem in the Linux kernel 2.6.38.5 and earlier does not properly restrict memory allocation by the (1) AGPIOC_RESERVE and (2) AGPIOC_ALLOCATE ioctls, which allows local users to cause a denial of service (memory consumption) by making many calls to these ioctls.

From the Ubuntu Security Team

Vasiliy Kulikov discovered that the AGP driver did not check the size of certain memory allocations. A local attacker with access to the video subsystem could exploit this to run the system out of memory, leading to a denial of service.

CAP_SYS_RAWIO is needed to exploit this, so is not security relevant. Ignoring.
