CVE-2017-16536

Published: 3 November 2017

The cx231xx_usb_probe function in drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted USB device.

From the Ubuntu Security Team

Andrey Konovalov discovered that the Conexant cx231xx USB video capture driver in the Linux kernel did not properly validate interface descriptors. A physically proximate attacker could use this to cause a denial of service (system crash).
