Unprivileged native apps running on a Whonix Workstation VM can obtain some host hw details. Example:
user@host:~$ grep 'model name' /proc/cpuinfo
model name : Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz
model name : Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz
user@host:~$
Oops. That’s the host CPU. And also shows that the VM can use only 2 cores.
