CVE-2011-1747 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.43% chance of exploitation in the next 30 days.
