6.5
CVSSv3
CVE-2017-15591
An issue exists in Xen 4.5.x up to and including 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.

CVE-2017-14431
Memory leak in Xen 3.3 up to and including 4.8.x allows guest OS users to cause a denial of service (ARM or x86 AMD host OS memory consumption) by continually rebooting, because certain cleanup is skipped if no pass-through device was ever assigned, aka XSA-207.
