NVD Description

Note: Versions mentioned in the description apply only to the upstream xen package and not the xen package as distributed by Ubuntu.

An issue was discovered in Xen through 4.14.x allowing x86 guest OS users to cause a denial of service (data corruption), cause a data leak, or possibly gain privileges because an AMD IOMMU page-table entry can be half-updated.
