FKIE_CVE-2011-2022

Vulnerability from fkie_nvd - Published: 2011-05-09 19:55 - Updated: 2026-06-16 23:30
Severity
Summary
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.
