## What is CVE-2005-3271?

CVE-2005-3271 is a low-severity denial of service vulnerability in Linux kernel, published on 20 Oct 2005. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Exec in Linux kernel 2.6 does not properly clear posix-timers in multi-threaded environments, which results in a resource leak and could allow a large number of multiple local users to cause a denial of service by using more posix-timers than specified by the quota for a single user.

## Which versions are affected by CVE-2005-3271?

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2005-3271 and fix it if it is affected.

What it is: CVE-2005-3271 is a low-severity denial of service vulnerability in Linux kernel, published on 20 Oct 2005. 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-2005-3271 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.
