Linus Torvalds ce114c8668 Just when you thought that all the speculation bugs were addressed and 
solved and the nightmare is complete, here's the next one: speculating
 after RET instructions and leaking privileged information using the now
 pretty much classical covert channels.
 
 It is called RETBleed and the mitigation effort and controlling
 functionality has been modelled similar to what already existing
 mitigations provide.
