SEV 펌웨어 취약점 이 저장소는 SEV 펌웨어의 취약점에 대한 익스플로잇을 포함합니다. 익스플로잇은 실행 중인 SEV-SNP 게스트의 임의 메모리를 복호화할 수 있습니다. 버전 1.55.16작성 시점 기준 최신에서 테스트되었습니다. 근본 원인 SEVINITEX 명령의 nvpaddr 필드는 펌웨어에 메모리 청크를 기증하는 데 사용될 수 있으며, 이를 통해 영구 플래시 대신 사용할 수 있습니다. SEV-SNP가 활성화된 경우 이 메모리는 FIRMWARE 상태여야 합니다. 펌웨어는 SEVINITEX 명령을 실행하는 동안 확인합니다...
