CVE-2021-28696
CVE-2021-28696 affects the Xen hypervisor. The issue arises from IOMMU identity mappings defined in ACPI for devices assigned to a guest: when a device is de-allocated from a guest, the identity mappings can be left in place, allowing the guest continued access to memory ranges it should no longe...

CVE-2021-28694
CVE-2021-28694 is described in the Citrix Hypervisor security update as a host denial-of-service issue triggered when a guest VM uses PCI passthrough with ACPI-declared memory regions that are identity-mapped. The vulnerability arises because such regions may bypass normal translation checks, pot...
