- **Exploited in the wild:** Not known
- **Login needed:** Not needed
- **Attackable:** Over the internet
- **Victim action needed:** Not needed

## What is CVE-2005-2872?

CVE-2005-2872 is a medium-severity vulnerability in Linux kernel, published on 9 Sep 2005. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The ipt_recent kernel module (ipt_recent.c) in Linux kernel before 2.6.12, when running on 64-bit processors such as AMD64, allows remote attackers to cause a denial of service (kernel panic) via certain attacks such as SSH brute force, which leads to memset calls using a length based on the u_int32_t type, acting on an array of unsigned long elements, a different vulnerability than CVE-2005-2873.

## Which versions are affected by CVE-2005-2872?

It affects 1 product.


Products: Linux kernel.

## How do I fix CVE-2005-2872?

Upgrade to a fixed version.

## Is CVE-2005-2872 being exploited?

There is no known exploitation of CVE-2005-2872 in the wild and no public exploit code.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2005-2872 and fix it if it is affected.

What it is: CVE-2005-2872 is a medium-severity vulnerability in Linux kernel, published on 9 Sep 2005. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2005-2872 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.
