More information came to light yesterday evening and overnight concerning the reported flaws in Intel and other processors. I am including numerous links to multiple sources, but some of the key updates include:
There are actually two architectural vulnerabilities in play – Meltdown and Spectre
This is more than an Intel problem – AMD and ARM chips are also affected to various degrees
Microsoft has released an emergency out-of-band patch overnight that begins to address some of the vulnerabilities
There are still many unknowns as to the extent of impact that will come from patching and/or rearchitecting OS/chipset interactions
