Descriptions

The networking implementation in the Linux kernel through 4.3.3, as used in Android and other products, does not validate protocol identifiers for certain protocol families, which allows local users to cause a denial of service (NULL function pointer dereference and system crash) or possibly gain privileges by leveraging CLONE_NEWUSER support to execute a crafted SOCK_RAW application.

La implementación de redes en el kernel de Linux hasta la versión 4.3.3, tal como se utiliza en Android y otros productos, no valida identificadores de protocolo para ciertas familias de protocolos, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero de función NULL y caída de sistema) o posiblemente obtener privilegios mediante el aprovechamiento de soporte CLONE_NEWUSER para ejecutar una aplicación SOCK_RAW manipulada.

A NULL pointer dereference flaw was found in the way the Linux kernel's network subsystem handled socket creation with an invalid protocol identifier. A local user could use this flaw to crash the system.
