issues that were discovered in previous releases:
+Hypervisor Crashed When Fuzzing HC_DESTROY_VM
+ The input 'vdev->pdev' shall be validated properly when handling HC_SET_PTDEV_INTR_INFO,
+ to insure physical device is linked to 'vdev', otherwise hypervisor will crash when fuzzing
+ hypercall HC_DESTROY_VM with crafted input.

+Hypervisor Crashed When Fuzzing HC_NOTIFY_REQUEST_FINISH
+ The input is not validated properly when handing this hypercall, 'vcpu_id' shall be
+ less than 'vm->hw.created_vcpus' instead of 'MAX_VCPUS_PER_VM'. When the software

Mitigation for Machine Check Error on Page Size Change
Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access. Malicious guest kernel could trigger this issue, CVE-2018-12207.
