Published: 2026-07-06 Description Description Severity Notes A virtualization vulnerability has been identified in the KVM x86 shadow paging and nested virtualization configurations. Because an attacker operating a virtual machine with nested virtualization could escape hypervisor boundary isolation to compromise the underlying physical host, any x86 virtual machine (whether nested or non-nested) hosted on an Intel-based server supporting nested virtualization is potentially exposed. What should I do? Google is deploying live hypervisor hotpatches across all managed Compute Engine host servers
