Intel promises to provide firmware updates by the end of next week for 90% of all CPU models it released in the past five years. The company said the updates will “render those systems immune from both exploits (referred to as Spectre and Meltdown )”” Intel said it already started shipping some of these CPU firmware updates to some of its partners. OEMs and other hardware vendors will then have to include these firmware updates in updates for their own products.”
