[German<\/a>]Intel released another batch of microcode updates (to OEMs) to close the Spectre V2 vulnerability for 6th, 7th and 8th generation Intel CPUs.<\/p>\n

<\/p>\n

\"\"After Intel had to withdraw microcode updates due to problems in January 2018, the first firmware was released again in early February 2018. In a note to the press<\/a> Intel announced, that:<\/p>\n

\n

production microcode updates to our OEM customers and partners for Kaby Lake- and Coffee Lake-based platforms, plus additional Skylake-based platforms. This represents our 6th<\/sup>, 7th<\/sup> and 8th<\/sup> Generation Intel\u00ae Core\u2122 product lines as well as our latest Intel\u00ae Core\u2122 X-series processor family. It also includes our recently announced Intel\u00ae Xeon\u00ae Scalable and Intel\u00ae Xeon\u00ae D processors for data center systems. <\/p>\n<\/blockquote>\n

OEMs must integrate the updates into their UEFI versions. For Linux, Intel's microcode updates (in the Linux Processor Microcode Data File) do not seem to have been made available yet.  <\/p>\n

Intel released some details<\/h2>\n

In a 14 pages Microcode Revision Guidance<\/a> (PDF), dated February 20, 2018 Intel has published a list of pending and released updates. <\/p>\n

The document shows that the Coffee Lake H\/S variants (8th generation), Gemini Lake (and some special processors) have been updated with microcode updates..<\/p>\n

\"Intel

The above table shows that 7th generation Kaby Lake CPUs (H\/S\/X\/G, U, Y variants) have also been updated. And various Skylake CPUs (6th generation) have also been provided with microcode updates according to the following illustration. <\/p>\n

The PDF document shows that further microcode updates are already being tested as beta by OEMs. A release should therefore take place in the coming days and weeks. German news site heise.de wrotes<\/a>, that the updates for Skylake processors (Core i-6000), that has been pulled on January 22, 2018 has been released again. These updates are not modified, Intel re-released them after additional tests. Dell EMC, Fujutsu and HP shall provide these microcode updates (from Januar 2018) already. <\/p>\n

\n

Intel also has a white paper Retpoline: A Branch Target<\/a> with information on mitigating attacks via Spectre-V2.  <\/p>\n<\/blockquote>\n

Microsoft Surface Pro 3 firmware update<\/h2>\n

Microsoft has also released a UEFI firmware update for Surface Pro 3, which is intended to harden the system against the meltdown and spectre attack methods. The firmware update can be downloaded here<\/a> (as mentioned here<\/a>). <\/p>\n","protected":false},"excerpt":{"rendered":"
