CVE-2021-3656
CVE-2021-3656 describes a flaw in the KVM hypervisor for AMD processors where the L1 guest can provide a VMCB with an improperly validated virt_ext field, allowing the L1 to disable VMLOAD/VMSAVE intercepts and VLS for the L2 guest. This enables the L2 guest to read/write portions of the host’s p...
