Descriptions

The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request.

La función x25_negotiate_facilities en net/x25/x25_facilities.c en el kernel de Linux en versiones anteriores a 4.5.5 no inicializa adecuadamente una estructura de datos determinada, lo que permite a atacantes obtener información sensible del kernel de memoria de pila a través de una petición de llamada X.25.
