Intel is releasing new firmware updates that should address Spectre vulnerabilities CVE-2017-5715 for Skylake processors. The Spectre attack allows user-mode applications to extract information from other processes running on the same system. The company provided beta releases for the updates to apply to other processors to customers and partners to conduct extensive tests before the final release. Intel seems to have a more clear idea about the cause of the problems observed after the deploy of the initial updates and release new microcode updates. Many companies rolled out patches to revert the Intel updates, including Red Hat and Microsoft.”]
