Will running programs on a virtual machine ruin the computer that is running it?

Question

Virtualization

I have a Windows 10 computer with an Oracle VM virtual box installed on it.
Ubuntu is installed on the virtual machine. On Ubuntu, I plan to do experiments, that is, learn low-level languages ​​and run programs that, as far as I know, can access the central processor. But there is such an idea, will my main computer on Windows 10 not be corrupted even if I mess up memory addresses and so on, I create things on Ubuntu inside a virtual machine.

Answer 1

I think that if the author finds an opportunity to damage his main OS from the guest OS, then he is a mega-cool hacker and you can safely start a technical security critical-bug in Oracle.

Answer 2

No. The main thing is not to connect a physical disk (but it’s not so easy to connect it).

Answer 3

Theoretically, the virtual machine emulates everything, and no actions can go outside.

No, nothing will

Answer 5

Well, if you are able to reproduce the Specter bug (and understand how it is reproduced) - then you can probably damage it :) otherwise it's unlikely :)
