Details
What privileges could be gained by an attacker who successfully exploited the vulnerability?
An attacker who successfully exploited this vulnerability could potentially gain elevated privileges on the host system beyond the guest virtual machine boundary.
What is the reason for the High Attack Complexity (AC:H) value in the CVSS score?
Successful exploitation requires the affected virtual machine to have multiple assigned graphics adapters with differing configurations. This prerequisite is outside the attacker's control.
