Review rev_b522ef2e38a04f28ae7b4bc848d37b71

{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/cpucap/cpu_aarch64.h`, which is a small AArch64 CPU-capability header that only declares `handle_cpu_env` behind compile-time guards and includes standard headers. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence-related logic; none are present in this target file.\nReviewed this header-only interface for ML-KEM/IndCPA primitives. It contains only function prototypes and namespace macros, with no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior present in the target file.\nReviewed `aws-lc/crypto/dilithium/pqcrystals_dilithium_ref_common/symmetric-shake.c`, which only defines two SHAKE-based stream initialization helpers that absorb a seed and nonce into Keccak state. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, or persistence/tampering logic.\nReviewed `aws-lc/crypto/fipsmodule/fips_shared_support.c`, which only defines a fixed 32-byte default FIPS integrity hash constant behind compile-time guards for shared-library FIPS builds. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `aws-lc/crypto/fipsmodule/gcc_fips_shared.lds`, a GNU linker script that defines `.text` and `.rodata` output sections and explicitly discards relocation and data-related sections. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
