Microsoft has released Intel firmware updates for all supported versions of Windows 10 that protect against attacks that exploit Microarchitectural Data Sampling (MDS) vulnerabilities.
On May 14, 2019, Intel uncovered a new vulnerability group in its processors, which it calls “microarchitectural data sampling” —Microarchitectural Data Sampling (MDS) or ZombieLoad. Vulnerabilities are associated with speculative execution attacks, such as Specter or Meltdown, discovered last year. This issue affects all modern Intel processors on servers, desktops and laptops.
