Intel recently announced that they have completed their validations and started to release microcode for recent CPU platforms related to Spectre Variant 3a (CVE-2018-3640: \"Rogue System Register Read (RSRE)\"), Spectre Variant 4 (CVE-2018-3639: \"Speculative Store Bypass (SSB)\"), L1TF (CVE-2018-3615, CVE-2018-3620, CVE-2018-3646: \"L1 Terminal Fault\"). In addition to microcode updates previously released in KB4100347<\/a>\u200b to address Spectre Variant 2 (CVE 2017-5715: \"Branch Target Injection\"), this update also includes microcode updates from Intel for the following CPUs.<\/p><\/blockquote>\n

Microsoft intends to offer additional microcode updates from Intel for this operating system via the KB article as soon as they are available for Microsoft. Vulnerability protection is enabled by default for Windows client systems, so no action is required.<\/p>\n

Please make sure that protection against Spectre Variant 2 for servers is enabled via the registry settings documented in the article Windows Server guidance to protect against speculative execution side-channel vulnerabilities<\/a>.<\/p>\n

Notes: Microsoft advises: Check with your device manufacturer and Intel through their websites for microcode recommendations for your device before applying this update to your device.<\/p><\/blockquote>\n

Addendum: Microcode update overview<\/h2>\n

I'm slowly losing track of when and where which Microcode update from Microsoft was released for Windows.

Maybe it'll help.<\/p>\n","protected":false},"excerpt":{"rendered":"
