CVE-2011-1745

Desbordamiento de enteros en la función agp_generic_insert_memory en los drivers /char/agp/generic.c del kernel de Linux con anterioridad a v2.6.38.5 permite a usuarios locales conseguir privilegios o causar una denegación de servicio ( fallo del sistema ) a través de una llamada ioctl manipulada a AGPIOC_BIND agp_ioctl.

Dan Rosenberg discovered that IRDA did not correctly check the size of buffers. On non-x86 systems, a local attacker could exploit this to read kernel heap memory, leading to a loss of privacy. Dan Rosenburg discovered that the CAN subsystem leaked kernel addresses into the /proc filesystem. A local attacker could use this to increase the chances of a successful memory corruption exploit. Kees Cook discovered that the IOWarrior USB device driver did not correctly check certain size fields. A local attacker with physical access could plug in a specially crafted USB device to crash the system or potentially gain root privileges. Various other issues were also addressed.
