**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** Successful exploitation of this vulnerability could allow a Hyper-V guest to affect the functionality of the Hyper-V host.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** This vulnerability requires that a user with an affected version of Windows access a malicious server. An attacker would have to host a specially crafted server share or website. An attacker would have no way to force users to visit this specially crafted server share or website, but would have to convince them to visit the server share or website, typically by way of an enticement in an email or chat message.
