Review rev_588ae07c0a7e40689eb2e95912d6fb2a

{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/ml_dsa/mldsa/common.h`, a macro-heavy internal configuration header for ML-DSA namespace, backend inclusion, and allocation wrappers. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/lhash/lhash.c`, which implements an in-memory hash table for insert/retrieve/delete/iteration with automatic resizing. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration logic, credential/secret access, dynamic code loading, obfuscation/packing, or persistence/tampering behavior.\nReviewed `aws-lc/crypto/rsa_extra/rsa_asn1.c`, which implements RSA public/private key ASN.1 parsing, encoding, and duplication helpers. I checked for install-time execution, hidden subprocesses, network or credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators; none were present in this file.\nReviewed the x86-64 ML-DSA reduction routine in `mldsa_reduce.S`, which performs in-place modular reduction on 256 signed 32-bit coefficients using AVX2 arithmetic and ABI save/restore code. I checked for install-time execution, hidden subprocesses, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
