The Google Project Zero project team, working with academics and industry researchers from several countries, publicly reported the above vulnerability for the first time on January 3, but major technology companies said they learned about it a few months ago. Google said it began deploying software patches for a variant of the Meltdown and Specter vulnerabilities from September last year, and in December developed a patch for the Specter # 2 variant that does not slow down system prerequisites It's harder to fix.

Microsoft has also released a patch for these vulnerabilities, but earlier this week admitted that its patch for Specter 2 variant would slow down some of the PC andserver, Where the performance of systems based on older Intel processors can drop significantly.
