Windows Sandbox and Intel CPU Speculative side channel vulnerabilities

Hi.


I've yet to try Windows 10 version 1903 (waiting for the final version to roll out). However I'm aware of the new Windows Sandbox feature and I'm excited about it.


I do have a question though.


In the light of the recent side channel speculative execution vulnerabilities of the Intel chips, be it Meltdown, Spectre, Spoiler, MDS, ZombieLoad, etc. - do they have the potential to weaken the sandbox security?


I am aware that Windows Sandbox will base itself on Hyper-V, but if these speculative execution vulnerabilities in Intel chips continue to unravel, do they have the possibility to affect the sandbox security by design?


Will future cpu flaws of this type render the windows sandbox security useless? Are there any permanent mitigations that could help prevent sandbox escape or data leaks from the sandbox via a speculative execution vulnerability?


Thank you in advance for your feedback!
