CVE-2023-2194 is a medium-severity memory corruption vulnerability in Fedoraproject Fedora, published on 20 Apr 2023. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2023-2194 and fix it if it is affected.

What it is: CVE-2023-2194 is a medium-severity memory corruption vulnerability in Fedoraproject Fedora, published on 20 Apr 2023. 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-2023-2194 in the wild and no public exploit code.

Affected product: Fedoraproject Fedora. 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.
