CVE-2011-2022: Linux Kernel

Medium severity, CVSS 6.9. EPSS: 0.4% chance of exploitation in the next 30 days.

The agp_generic_remove_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 does not validate a certain start parameter, which allows local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_UNBIND agp_ioctl ioctl call, a different vulnerability than CVE-2011-1745.
