CVE-2017-15102

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

It was discovered that an out-of-bounds write vulnerability existed in the Flash-Friendly File System in the Linux kernel. An attacker could construct a malicious file system that, when mounted, could cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition leading to a use-after-free vulnerability existed in the ALSA PCM subsystem of the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
