- **Exploited in the wild:** Not known
- **Login needed:** An administrator
- **Attackable:** Local or same network only
- **Victim action needed:** Not needed
- **Fix available:** No
- **Published:** 27 Jul 2019

## What is CVE-2010-5332?

CVE-2010-5332 is a medium-severity memory corruption vulnerability in Linux kernel, published on 27 Jul 2019. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

In the Linux kernel before 2.6.37, an out of bounds array access happened in drivers/net/mlx4/port.c. When searching for a free entry in either mlx4_register_vlan() or mlx4_register_mac(), and there is no free entry, the loop terminates without updating the local variable free thus causing out of array bounds access.

Weakness: CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2010-5332 and fix it if it is affected.

What it is: CVE-2010-5332 is a medium-severity memory corruption vulnerability in Linux kernel, published on 27 Jul 2019. 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-2010-5332 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.
