What is CVE-2007-5093?

CVE-2007-5093 is a medium-severity denial of service vulnerability in Linux kernel, published on 26 Sep 2007. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

Official 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.

Weakness: CWE-399
