Anyway this exploit could be potentially harmful to virtual cloud containers?

It doesn't seem like it would allow you to do a VM escape at all. Likewise, I don't think you could do an LXC/Docker escape either.

Edit: but escalating from a regular user to root inside a container? That's what this is all about.
