Check this codebase for CVE-2021-34380 and fix it if it is affected.

What it is: CVE-2021-34380 is a high-severity memory corruption vulnerability in NVIDIA Jetson TX1, TX2 series, TX2 NX, AGX Xavier series, Xavier NX, Nano and Nano 2GB, published on 30 Jun 2021. 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-2021-34380 in the wild and no public exploit code.

Affected product: NVIDIA Jetson TX1, TX2 series, TX2 NX, AGX Xavier series, Xavier NX, Nano and Nano 2GB. 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.
