Review rev_f6e05da64fe44781b30dac32bc9b1a5f

{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/bn/add.c`, which implements BIGNUM signed and unsigned addition/subtraction helpers and word-level arithmetic. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/fipsmodule/ml_dsa/mldsa/sys.h`, which is a platform-detection and compile-time configuration header defining architecture, endianness, alignment, CET, and test helper macros plus a default capability check that returns 1. I checked for install-time hooks, hidden subprocess execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence tampering, and other supply-chain indicators, and found none in this file.\nGenerated ARM/NEON assembly for GHASH in AWS-LC/OpenSSL style, implementing `_gcm_init_v8`, `_gcm_gmult_v8`, and `_gcm_ghash_v8`. I checked the file for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.\nReviewed the ARM64 assembly implementation of `bignum_mul_4_8`, which is a straight-line Karatsuba-style big-number multiply that reads two input buffers and writes the product to the output buffer. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.",
