CVE-2017-15102

Estado: ModificadaMedia (6.3)—

La función tower_probe en drivers/usb/misc/legousbtower.c en el kernel de Linux en versiones anteriores a la 4.8.1 permite que usuarios locales (que estén tan cerca físicamente como para insertar un dispositivo USB manipulado) obtengan privilegios aprovechando una condición de write-what-where que ocurre tras una condición de carrera y una desreferencia de puntero NULL
