Description:
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.
