A new technical paper titled “VMSCAPE: Exposing and Exploiting Incomplete Branch Predictor Isolation in Cloud Environments” was published by researchers at ETH Zurich. “Virtualization is a cornerstone ...
In the world of modern CPUs, speculative execution, where a processor guesses ahead on branches and executes instructions before the actual code path is confirmed, has long been recognized as a ...
The new attack method can leak privileged kernel memory on CPUs released in the past six years that have hardware mitigations for speculative execution and branch injection attacks like Spectre. Six ...
