Descriptions

The bcm_release function in net/can/bcm.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 bcm_release en net/can/bcm.c del kernel de linux en versiones anteriores a v2.6.39-rc6 no valida correctamente una estructura de toma de datos, lo cual permite a usuarios locales causar una denegación de servicio ( desreferenciar un puntero NULL ) o posiblemente tener un impacto no especificado a través de una operación de liberación manipulada.
