조치방안
제3자 참조와 수정 버전 값(5.15.210, 6.1.176, 6.6.140, 6.12.88, 6.18.30, 7.0.7)은 보조 근거로만 사용하고, 공급사 공식 보안 권고에서 조치 기준을 재확인합니다.
조치 후 확인사항
패치 후 같은 명령으로 전체 버전을 다시 확인해 Linux Linux, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 10.0 Extended Update Support 5.15.210, 6.1.176, 6.6.140, 6.12.88, 6.18.30, 7.0.7 기준을 충족하는지 확인합니다. 이어서 메모리 손상 관련 오류·공격 흔적이 새로 발생하지 않는지 확인합니다.
