New AMD Side Channel Attacks Discovered, Impacts Zen Architecture (AMD Responds)

A new paper released by the Graz University of Technology details two new "Take A Way" attacks, Collide+Probe and Load+Reload, that can leak secret data from AMD processors by manipulating the L1D cache predictor. The researchers claim that the vulnerability impacts all AMD processors from 2011 to 2019, meaning that the Zen microarchitecture is also impacted. (PDF) The university says it disclosed
