Descriptions

The tower_probe function in drivers/usb/misc/legousbtower.c in the Linux kernel before 4.8.1 allows local users (who are physically proximate for inserting a crafted USB device) to gain privileges by leveraging a write-what-where condition that occurs after a race condition and a NULL pointer dereference.

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
