Per the paper, this looks like an attack against speculated instructions that modify the store forward buffer. The details aren't super clear, but that seems extremely unlikely to survive a context switch. In practice this is probably only an attack against hyperthread code running simultaneously on the same CPU, which I'd expect cloud hosts to have eliminated long ago.
