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 4.5.x through 4.9.x allowing attackers (who control a stub domain kernel or tool stack) to cause a denial of service (host OS crash) because of a missing comparison (of range start to range end) within the DMOP map/unmap implementation.
