I wouldn't assume that. I think the big deal here is that they managed to break out of the Windows sandbox; that's what makes the exploit particularly interesting. The same vulnerability could exist on Linux too, but they just didn't invest the time in developing and demoing an exploit there too. Or maybe not. I'm just saying, we can't assume either way.
