A vulnerability was found in the Linux kernel. There is an information leak in the x25 module (net/x25/x25_facilities.c). Stack object "dte_facilities" is allocated in x25_rx_call_request(), which is supposed to be initialized in x25_negotiate_facilities. However, 5 fields (8 bytes in total) are not initialized. This object is then copied to userland via copy_to_user, thus info leak occurs.
