## What is CVE-2024-6031?

CVE-2024-6031 is a high-severity memory corruption vulnerability in Tesla Model S, published on 30 Apr 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Tesla Model S oFono AT Command Heap-based Buffer Overflow Code Execution Vulnerability. This vulnerability allows local attackers to execute arbitrary code on affected Tesla Model S vehicles. An attacker must first obtain the ability to execute code on the target modem in order to exploit this vulnerability.
 
The specific flaw exists within the parsing of responses from AT commands. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-23198.

Weakness: CWE-122 (Heap-based Buffer Overflow)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-6031 and fix it if it is affected.

What it is: CVE-2024-6031 is a high-severity memory corruption vulnerability in Tesla Model S, published on 30 Apr 2025. 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-2024-6031 in the wild and no public exploit code.

Affected product: Tesla Model S. 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.
