“This represents our 6th, 7th, and 8th Generation Intel Core product lines as well as our latest Intel Core X-series processor family. It also includes our recently announced Intel Xeon Scalable and Intel Xeon D processors for data center systems,” said Navin Shenoy, general manager of the Data Center Group at Intel Corporation, in a post.

Intel has been releasing updates after the news broke about the vulnerabilities. This release follows microcode updates for other Skylake-based platforms in early February. That came after Intel’s January advisory to stop deploying initial firmware updates that addressed Spectre (variant 2) due to a higher than expected incidence of reboots and other unpredictable system behavior.

Shenoy advised users to implement OEM firmware updates as the OEMs release them.

Intel also has a constantly updated document sharing information into the current situation regarding Spectre patches and released microcode.

Microcode updates for older processors using the Broadwell and Haswell cores are still in “beta.”

Shenoy also noted the existence of a Google-developed mitigation technique for Variant 2 called Retpoline.

For more information on Retpoline, Intel released a white paper with more details.
