CVE-2023-20569 Information disclosure in 1st Gen AMD EPYC™ Processors
Medium 4.7
Published
Updated
Check this codebase for CVE-2023-20569 and fix it if it is affected.
What it is: CVE-2023-20569 is a medium-severity vulnerability in Amd Epyc 72f3 Firmware, published on 8 Aug 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-2023-20569 in the wild and no public exploit code.
Affected product: Amd Epyc 72f3 Firmware. 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.
