Beijing time January 12th morning news, Alphabet Google's Department said on Thursday, the company has developed patches for repairing Spectre and Meltdown chips security vulnerabilities last year, and its cloud service speed has not slowed down.

These two vulnerabilities affect Intel, AMD and ARM chips. Hackers can use these vulnerabilities to read and store computers and steal passwords, so that smart phones, computers and services are at risk.

Google Project Zero researchers collaborate with academics and industry researchers from many countries, first reported publicly about the above vulnerabilities in January 3rd, but large technology companies said they had learned the information several months ago. Google said it began deploying software patches for a variant of Meltdown vulnerabilities and Spectre vulnerabilities since last September, and developed patches for Spectre vulnerability two in December. The variant is more difficult to repair without slowing down the speed of the system operation.

Microsoft has also released patches for these vulnerabilities. But earlier this week, it acknowledged that its patch for the Spectre bug two variant will slow down some PC and server speed, and the performance of the system running on the old Intel processor will decrease significantly.

Intel said that the company will release patches for 90% of the 5 years old chips before January 15th, and then will focus on providing patches for the older chips.
