CVE-2011-1746

Multiples desbordamientos de enteros en las funciones agp_allocate_memory y agp_create_user_memory en los drivers /char/agp/generic.c del kernel de Linux con anterioridad a v2.6.38.5 permite a los usuarios locales provocar desbordamientos de búfer, y causar en consecuencia, una denegación de servicio ( caída del sistema ) o, posiblemente, tener un impacto no especificado, a través de vectores relacionados con las llamadas que especifican un amplio número de páginas de memoria.

It was discovered that KVM did not correctly initialize certain CPU registers. A local attacker could exploit this to crash the system, leading to a denial of service. Thomas Pollet discovered that the RDS network protocol did not check certain iovec buffers. A local attacker could exploit this to crash the system or possibly execute arbitrary code as the root user. Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Various other issues were also addressed.
