Reject malformed ML-DSA signing inputs

Summary

  • Reject short external-mu inputs before copying mu in internal signing and verification.
  • Reject nonzero context length with a NULL context pointer at the domain-separation prefix boundary.
  • Add focused unit regression tests for the malformed external-mu and domain-prefix cases.

Verification

  • Pre-fix make run_unit_44 failed after adding the targeted malformed-input regression test.
  • make run_unit_44
  • make run_unit
  • make run_func

Note: the focused regression test and broader unit/functional runs above were collected on the tidy pre-replay patch commit. This PR branch was then cleanly replayed onto current upstream main; post-replay git diff --check passes, but the tests have not been rerun on the replayed commit yet.

This work was completed by Trail of Bits as part of the Patch The Planet project in collaboration with OpenAI. The issue was identified primarily by the Codex coding agent, and manually reviewed before submission.

Reject malformed ML-DSA signing inputs
3ae19b5 
Reject short external-mu inputs before copying mu in internal signing and
verification, and reject nonzero context length with a NULL context pointer
at the domain-separation prefix boundary.

Add focused unit regression tests for the malformed external-mu and
domain-prefix cases without bundling unrelated SHAKE/output-cleanup tests.

Verification:

- pre-fix `make run_unit_44` failed after adding the targeted malformed-input
  regression test

- make run_unit_44

- make run_unit

- make run_func

Keep malformed-input unit test reduced-api safe
83c27aa 
Keep the signing-side short external-mu unit regression test enabled when the build exposes keygen and sign APIs but compiles out verification. Guard only the verify-side malformed external-mu assertion so reduced-api keygen+sign builds do not reference verify_internal.

Verification:

- pre-fix focused reduced-api unit check failed with an implicit declaration of verify_internal under MLD_CONFIG_NO_VERIFY_API

- focused reduced-api unit check passed for keygen+sign/no-verify

- focused reduced-api-reduce-ram unit check passed for keygen+sign/no-verify

- nix develop .#ci -c lint
