멜트다운 버그와 스펙터 보안버그에 대한 각 프로세서별 정리

Everything We Know About The Intel, AMD & ARM CPU Bug! - 지금까지 알려진 인텔, AMD, ARM CUP 버그목록

• Variant 1 : Bounds Check Bypass (CVE-2017-5753)
• Variant 2 : Branch Target Injection (CVE-2017-5715)
• Variant 3 : Rogue Data Cache Load (CVE-2017-5754)

Variant 1은 현존하는 모든 CPU가 전부 해당이 되며 AMD의 경우 리눅스에만 해당하며 OS패치등으로 해결이 가능합니다만 인텔은 완전한 해결이 불가능합니다

AMD는 Variant 2,3에서 해당 내역이 없기 때문에 지금까지 밝혀진 CPU 제조사 중 가장 안전한 회사로 결론이 났습니다

 

하지만 인텔은 Variant 1 ,2,3 전부 해당 되기때문에 심각한 문제로 남아 새로운 아키텍쳐를 적용하기 까지 약 4년 이상 후에나 해결될 것으로 보입니다

ARM 소식이 늦게 업데이트 되어가지만 예상보다 문제가 되는 모델이 점점 늘어나고 있습니다

What Processors Are Affected? Updated!

 The Speculative Execution CPU Bug Variant 1, targeted by the Spectre exploit, has been confirmed to affect these AMD, ARM and Intel processors : 

AMD Ryzen family of processors

AMD FX 8000 series processors

AMD 9000 series APUs

Apple A4, A5, A5X, A6, A6X, A7, A8, A8X, A9, A9X, A10 Fusion, A10X Fusion and A11 Bionic SoCs.

ARM Cortex-A75, Cortex-A73, Cortex-A72, Cortex-A57,  Cortex-A17, Cortex-A15, Cortex-A9, Cortex-A8, Cortex-R8, and Cortex-R7  processors

1st, 2nd, 3rd, 4th, 5th, 6th, 7th and 8th Gen Intel Core processors

Intel Xeon E-1200 v5 and v6 family of processors

Intel Xeon W processors

Intel Pentium G processors

Intel Atom C3000 and E3900 processors

Intel Pentium (Apollo Lake) processors

Intel Celeron G, N and J series processors

 

The Speculative Execution CPU Bug Variant 2, targeted by the Spectre exploit, has been confirmed to affect only ARM and Intel processors : 

ARM Cortex-A75, Cortex-A73, Cortex-A72, Cortex-A57,  Cortex-A17, Cortex-A15, Cortex-A9, Cortex-A8, Cortex-R8, and Cortex-R7  processors

Intel Xeon E-1200 v5 and v6 family of processors

Intel Xeon W processors

Intel Pentium G processors

Intel Atom C3000 and E3900 processors

Intel Pentium (Apollo Lake) processors

Intel Celeron G, N and J series processors

 

The Speculative Execution CPU Bug Variant 3, targeted by the Meltdown exploit, has been confirmed to affect only Intel processors and one ARM processor : 

ARM Cortex-A75

1st, 2nd, 3rd, 4th, 5th, 6th, 7th and 8th Gen Intel Core processors

Intel Xeon E-1200 v5 and v6 family of processors

Intel Xeon W processors

Intel Pentium G processors

Intel Atom C3000 and E3900 processors

Intel Pentium (Apollo Lake) processors

Intel Celeron G, N and J series processors

 

The Speculative Execution CPU Bug Variant 3a, targeted by the Meltdown exploit, has been confirmed to affect only some ARM processors : 

ARM Cortex-A72, Cortex-A57 and Cortex-A15 processors

 

To summarise, vulnerable Intel processors are affected by all three variants of the bug, while vulnerable AMD and ARM processors are only affected by the first variant, with a small number of ARM processors affected by Variant 3 or Variant 3a of the bug.

Apple confirmed that “all Mac systems and iOS devices are affected“.

애플 모든 제품 (아이폰, 아이패드)에 Variant 1, 2, 3 전부 해당되는 것으로 결론이 나오고 있습니다
