Check this codebase for CVE-2023-4263 and fix it if it is affected.
What it is: CVE-2023-4263 is a high-severity vulnerability in Zephyrproject Zephyr, published on 13 Oct 2023.
Exploitation: There is no known exploitation of CVE-2023-4263 in the wild and no public exploit code.
Affected product: Zephyrproject Zephyr. 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.
