CVE-2015-7814

Name of the Vulnerable Software and Affected Versions Xen versions prior to 4.7

Description A race condition exists in the relinquish memory function, allowing local domains with partial management control to cause a denial of service, resulting in a host crash. This can be achieved through vectors involving the destruction of a domain and using the XENMEM decrease reservation function to reduce the memory of the domain.
