DescriptionThe disconnect method in the Philips USB Webcam (pwc) driver in Linux kernel 2.6.x before 18.104.22.168 "relies on user space to close the device," which allows user-assisted local attackers to cause a denial of service (USB subsystem hang and CPU consumption in khubd) by not closing the device after the disconnect is invoked. NOTE: this rarely crosses privilege boundaries, unless the attacker can convince the victim to unplug the affected device.
