Summary: the disconnect method in the philips usb webcam (pwc) driver in linux kernel 2.6.x before 2.6.22.6 "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.
