Microsoft releases Spectre fixes for Windows 10 on Skylake CPUs

Microsoft is pushing out another round of security updates to mitigate data-leaking Spectre side-channel vulnerabilities. These are just for some devices running on Skylake CPUs and Windows 10 Fall Creators Update or Windows Server version 1709.

Specifically, the update will give those machines patches for CVE 2017-5715, also known as Spectre Variant 2. The branch target injection flaw would potentially allow malware on a PC or server to steal sensitive data, such as passwords, from kernel, hypervisor, or application memory.

The Skylake fixes are part of a larger line of microcode updates for the Spectre flaws that Intel is planning to roll out in the coming weeks. Chipzilla said people should obtain the security patches from their computer manufacturers, or via Microsoft.

Microsoft also gave an update on its work to address the compatibility issues that have arisen between some antivirus apps and its Meltdown/Spectre mitigations.
