Analysis and mitigation of speculative store bypass (CVE-2018-3639)

In January, 2018, Microsoft published an advisory and security updates for a new class of hardware vulnerabilities involving speculative execution side channels known as Spectre and Meltdown. In this blog post, we will provide a technical analysis of an additional subclass of speculative executio...

VMware vSphere, Workstation and Fusion updates enable Hypervisor-Assisted Guest Mitigations for Speculative Store Bypass issue.

vCenter Server, ESXi, Workstation, and Fusion update speculative execution control mechanism for Virtual Machines VMs. As a result, a patched Guest Operating System GOS can remediate the Speculative Store bypass issue CVE-2018-3639 using the Speculative-Store-Bypass-Disable SSBD control bit. This...
