Descriptions

The treo_attach function in drivers/usb/serial/visor.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a (1) bulk-in or (2) interrupt-in endpoint.

La función treo_attach en drivers/usb/serial/visor.c en el kernel de Linux en versiones anteriores a 4.5 permite a atacantes físicamente próximos causar una denegación de servicio (referencia a puntero NULL y caída del sistema) o posiblemente tener otro impacto no especificado mediante la inserción de un dispositivo USB que carece de punto final en (1) bulk-in o (2) interrupt-in.

Linux kernel version 3.10.0-229.20.1.el7.x86_64 crashes on presentation of a buggy USB device requiring the visor (treo_attach) driver.
