How to fix?

There is no fixed version for xen.

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). The p2m_teardown function in arch/arm/p2m.c in Xen 4.4.x through 4.6.x allows local guest OS users with access to the driver domain to cause a denial of service (NULL pointer dereference and host OS crash) by creating concurrent domains and holding references to them, related to VMID exhaustion.
