Windows Hyper-V Discrete Device Assignment (DDA) Denial of Service Vulnerability

The Windows 11 installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities:

  - A denial of service (DoS) vulnerability. An attacker can     exploit this issue to cause the affected component to     deny system or application services. (CVE-2021-41356,     CVE-2021-42274, CVE-2021-42284)

  - A remote code execution vulnerability. An attacker can     exploit this to bypass authentication and execute     unauthorized arbitrary commands. (CVE-2021-26443,     CVE-2021-38666, CVE-2021-41378, CVE-2021-42276,     CVE-2021-42279)

  - An elevation of privilege vulnerability. An attacker can     exploit this to gain elevated privileges.
    (CVE-2021-36957, CVE-2021-41366, CVE-2021-41367,     CVE-2021-41370, CVE-2021-41377, CVE-2021-41379,     CVE-2021-42277, CVE-2021-42280, CVE-2021-42283,     CVE-2021-42285)

  - An information disclosure vulnerability. An attacker can     exploit this to disclose potentially sensitive     information. (CVE-2021-38631, CVE-2021-38665,     CVE-2021-41371)

The remote Windows host is missing security update.  See Vendor Advisory for KB5007205

The remote Windows host is missing security update 5007206.
