## What is CVE-2013-4514?

CVE-2013-4514 is a medium-severity memory corruption vulnerability in Linux kernel, published on 12 Nov 2013. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Multiple buffer overflows in drivers/staging/wlags49_h2/wl_priv.c in the Linux kernel before 3.12 allow local users to cause a denial of service or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability and providing a long station-name string, related to the (1) wvlan_uil_put_info and (2) wvlan_set_station_nickname functions.

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-2013-4514 and fix it if it is affected.

What it is: CVE-2013-4514 is a medium-severity memory corruption vulnerability in Linux kernel, published on 12 Nov 2013. 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-2013-4514 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.
