Descriptions

drivers/input/serio/i8042.c in the Linux kernel before 4.12.4 allows attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact because the port->exists value can change after it is validated.

drivers/input/serio/i8042.c en el kernel de Linux en versiones anteriores a la 4.12.4 permite que atacantes provoquen una denegación de servicio (desreferencia de puntero NULL y cierre inesperado del sistema) o que, posiblemente, tengan otro tipo de impacto sin especificar debido a que el valor port->exists puede cambiar tras ser validado.
