## What is CVE-2021-46750?

CVE-2021-46750 is a low-severity vulnerability in AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics, published on 6 Sep 2025. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Failure to validate the address and size in TEE (Trusted Execution Environment) may allow a malicious x86 attacker to send malformed messages to the graphics mailbox resulting in an overlap of a TMR (Trusted Memory Region) that was previously allocated by the ASP bootloader leading to a potential loss of integrity.

Weakness: CWE-190 (Integer Overflow or Wraparound)

Affected product: AMD Athlon™ 3000 Series Mobile Processors with Radeon™ Graphics. 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.
