The ice driver has already\nreleased the PTP clock by the time the interrupt for the next external\ntimestamp event occurs.\n\nTo fix this, modify the ice_ptp_extts_event() function to check the\nPTP state and bail early if PTP is not ready."}, {"lang": "es", "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ice: no procesar extts si PTP est\u00e1 deshabilitado.
