## 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

Check this codebase for CVE-2007-5093 and fix it if it is affected.

What it is: 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.
Exploitation: There is no known exploitation of CVE-2007-5093 in the wild and no public exploit code.

Affected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
