## What is CVE-2025-8474?

CVE-2025-8474 is a medium-severity memory corruption vulnerability in Alpine iLX-507, published on 1 Aug 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Alpine iLX-507 CarPlay Stack-based Buffer Overflow Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Alpine iLX-507 devices. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the implementation of the Apple CarPlay protocol. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-26318.

Weakness: CWE-121 (Stack-based Buffer Overflow)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2025-8474 and fix it if it is affected.

What it is: CVE-2025-8474 is a medium-severity memory corruption vulnerability in Alpine iLX-507, published on 1 Aug 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-2025-8474 in the wild and no public exploit code.

Affected product: Alpine iLX-507. 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.
