## What is CVE-2007-3724?

CVE-2007-3724 is a low-severity denial of service vulnerability in Microsoft Windows Xp, published on 12 Jul 2007. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

The process scheduler in the Microsoft Windows XP kernel does not make use of the process statistics kept by the kernel, performs scheduling based on CPU billing gathered from periodic process sampling ticks, and gives preference to "interactive" processes that perform voluntary sleeps, which allows local users to cause a denial of service (CPU consumption), as described in "Secretly Monopolizing the CPU Without Superuser Privileges."

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2007-3724 and fix it if it is affected.

What it is: CVE-2007-3724 is a low-severity denial of service vulnerability in Microsoft Windows Xp, published on 12 Jul 2007. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2007-3724 in the wild and no public exploit code.

Affected product: Microsoft Windows Xp. 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.
