**According to the CVSS metric, the attack vector is network (AV:N). How could an attacker exploit this vulnerability?** As an authenticated user, the attacker could send a specially crafted string of data over the network, causing the application to crash.

**According to the CVSS metric, successful exploitation of this vulnerability has a high impact on availability (A:H). What does that mean for this vulnerability??** An attacker can send specially crafted packets which could impact availability of the service resulting in Denial of Service (DoS).

**According to the CVSS metric, successful exploitation of this vulnerability has a high impact on availability (A:H). What does that mean for this vulnerability??** An attacker can send specially crafted packets which could impact availability of the service resulting in Denial of Service (DoS).

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

**According to the CVSS metric, successful exploitation of this vulnerability has a high impact on availability (A:H). What does that mean for this vulnerability??** An attacker can send specially crafted packets which could impact availability of the service resulting in Denial of Service (DoS).

**According to the CVSS metric, successful exploitation of this vulnerability has a high impact on availability (A:H). What does that mean for this vulnerability??** An attacker can send specially crafted packets which could impact availability of the service resulting in Denial of Service (DoS).

**Are there any additional steps that I need to follow to be protected from this vulnerability?** The changes to address this vulnerability updated Virtual Secure Mode components. The policy described in Guidance for blocking rollback of Virtualization-based Security (VBS) related security updates has been updated to account for the latest changes. If you deployed this policy, then you'll need to redeploy using the updated policy.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** A successful exploitation of this vulnerability via a medium integrity level exploit could allow an attacker to gain unauthorized access to system-level resources, potentially modify kernel memory, and execute arbitrary code with kernel-level privileges. This could lead to a full compromise of the system’s integrity, confidentiality, and availability.
