## What is CVE-2005-1768?

CVE-2005-1768 is a low-severity vulnerability in Linux kernel, published on 11 Jul 2005. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Race condition in the ia32 compatibility code for the execve system call in Linux kernel 2.4 before 2.4.31 and 2.6 before 2.6.6 allows local users to cause a denial of service (kernel panic) and possibly execute arbitrary code via a concurrent thread that increments a pointer count after the nargs function has counted the pointers, but before the count is copied from user space to kernel space, which leads to a buffer overflow.

## Which versions are affected by CVE-2005-1768?

It affects 1 product.


Products: Linux kernel.

## How do I fix CVE-2005-1768?

Upgrade to a fixed version.

## Is CVE-2005-1768 being exploited?

There is no known exploitation of CVE-2005-1768 in the wild and no public exploit code.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2005-1768 and fix it if it is affected.

What it is: CVE-2005-1768 is a low-severity vulnerability in Linux kernel, published on 11 Jul 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-2005-1768 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.
