Check this codebase for CVE-2025-6202 and fix it if it is affected.
What it is: CVE-2025-6202 is a high-severity vulnerability in SK Hynix DDR5, published on 15 Sep 2025.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-6202 exists.
Affected product: SK Hynix DDR5. 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.
