long running loops in grant table handling In order to properly monitor resource use, Xen maintains information on the grant mappings a domain may create to map grants offered by other domains. In the process of carrying out certain actions, Xen would iterate over all such entries, including ones...

CVE-2021-28695

CVE-2021-28695 affects the Xen hypervisor (IOMMU page mapping) on AMD systems. The issue arises when firmware specifies discontinuous memory ranges that are identity-mapped during translation, allowing a guest to retain access to memory ranges it should not access after device de-assignment. Docu...

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...
