Both Microsoft and Google are warning of another bug in computer processors. It's similar to previous bugs known as 'Spectre' and 'Meltdown'. For now the new issue has the less dramatic codenames 'Speculative Store Bypass Variant 4' and ... 'CVE-2018-3639'. As with Spectre and Meltdown , it involves a processor function known as speculative execution that's meant to improve computation processes.
