Researchers revealed serious flaws in modern processors that could affect practically every Intel computer released in the last two decades — and the AMD and Arm chips in your laptops, tablets and phones, too. CNET reported 1/4/2018 and other IT security sources.
Microsoft released a patch to address a number of issues, including a reported CPU vulnerability issue on Wednesday 3 January 2018.
