After a long embargo period of 9 months we made our paper RIDL: Rogue In-Flight Data Load available to the general public. RIDL introduces a new class of speculative execution attacks that can leak any “in-flight” data available in the CPU.
More information (including some nice demo videos) are available at https://mdsattacks.com. We have also released a tool that you can use to see how vulnerable your computer is to different speculative execution attacks.
