Technical details

(2) can be exploited via creating multiple machine accounts.

Denial of service caused by exploitation of (9) can lead to data loss.

Exploitation of vulnerability (12) can cause allowance of unintended network traffic. Customers with disabled Hyper-V role are not affected to this vulnerability.

To exploit vulnerabilities (2, 4, 6, 7, 10, 11) attacker must be logged in and specially for vulnerability (2) have sufficient permissions to create accounts.
