Descriptions

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.

La función agp_generic_remove_memory en los drivers /char/agp/generic.c del kernel de Linux con anterioridad a v2.6.38.5 no valida un parámetro de inicio determinado, lo que permite a usuarios locales conseguir privilegios o causar una denegación de servicio ( fallo del sistema ) a través de una llamada manipulada AGPIOC_UNBIND agp_ioctl ioctl, es una vulnerabilidad diferente de CVE -2011- 1745.
