    Intel Optimizing Its MDS Mitigation Handling To Avoid Possible Kernel Data Leaking

    Phoronix: Intel Optimizing Its MDS Mitigation Handling To Avoid Possible Kernel Data Leaking

    An Intel engineer on Friday posted a set of Linux kernel patches that are working to refine the Microarchitectural Data Sampling (MDS) mitigation handling for the Linux kernel to better protect some kernel data and also some very subtle performance benefits...

      I wonder if this isn't an attempt to fix the problems identified in some recent work that puts some data behind the issue I keep pointing out: mitigations aren't fixes. The problem still remains. Spectre is still going to be exploitable, it's just a matter of picking your way around the roadblocks with determination.
