## What is CVE-2005-0937?

CVE-2005-0937 is a low-severity vulnerability in Linux kernel, published on 30 Mar 2005. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Some futex functions in futex.c for Linux kernel 2.6.x perform get_user calls while holding the mmap_sem semaphore, which could allow local users to cause a deadlock condition in do_page_fault by triggering get_user faults while another thread is executing mmap or other functions.

## Which versions are affected by CVE-2005-0937?

It affects 1 product.


Products: Linux kernel.

## How do I fix CVE-2005-0937?

Apply the vendor's patch.

## Is CVE-2005-0937 being exploited?

There is no known exploitation of CVE-2005-0937 in the wild and no public exploit code.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2005-0937 and fix it if it is affected.

What it is: CVE-2005-0937 is a low-severity vulnerability in Linux kernel, published on 30 Mar 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-2005-0937 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.
