In a press release published on Tuesday, Intel announced it resumed the deployment of CPU microcode firmware updates. These updates are meant to mitigate the Spectre Variant 2 vulnerability —CVE-2017-5715. The Meltdown (CVE-2017-5754) and Spectre variant 1 (CVE-2017-5753) vulnerabilities —which became public at the start of the year— were fixed through software updates at the OS level. Intel paused the deployment of Spectre v2 CPU microcode updates on January 22 after receiving reports that the initial patches caused high system reboot rates on some systems, causing problems especially with Intel-based servers deployed in data centers.
