Whenever you have sharing, you usually have side channels. We're going to see more and more of this until we have much better hardware isolation.
This is a kind of obvious variant of Rowhammer, which hasn't generally been fixed AFAIK.
Hardware in the late 2010s seems a bit like Windows in the late 1990s - a house of cards waiting to collapse, but the dominant vendors know that very few customers are willing to pay more for security and reliability vs. performance/features/new and shiny.
(So if we're lucky then we'll end up with a "more secure" version of hardware that is analogous to... Windows Vista.)
