CVE-2015-7515

Published: 27 April 2016

The aiptek_probe function in drivers/input/tablet/aiptek.c in the Linux kernel before 4.4 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted USB device that lacks endpoints.

From the Ubuntu Security Team

Ralf Spenneberg discovered that the Aiptek Tablet USB device driver in the Linux kernel did not properly sanity check the endpoints reported by the device. An attacker with physical access could cause a denial of service (system crash).
