Descriptions

The raw_release function in net/can/raw.c in the Linux kernel before 2.6.39-rc6 does not properly validate a socket data structure, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted release operation.

La función raw_release en net/can/raw.c en el Kernel de Linux anterior a v2.6.39-rc6 no valida adecuadamente una estructura de datos socket, lo que permite a usuarios locales provocar una denegación de servicio (desreferencia a puntero NULL) o posiblemente tener otro impacto no especificado a través de una liberación de operación.
