**Are there any further actions I need to take to be protected from relay attacks?** The security updates released on September 9, 2025 enable support for auditing SMB client compatibility for SMB Server signing as well as SMB Server EPA. This allows customers to assess their environment and identify any potential device or software incompatibility issues before deploying the hardening measures that are already supported by SMB Server. Please see https://support.microsoft.com/help/5066913 for more information.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** In this case, a successful attack could be performed from a low privilege Hyper-V guest. The attacker could traverse the guest's security boundary to execute code on the Hyper-V host execution environment.

Access of resource using incompatible type ('type confusion') in Windows Defender Firewall Service allows an authorized attacker to elevate privileges locally.

Protection mechanism failure in Windows MapUrlToZone allows an unauthorized attacker to bypass a security feature over a network.

Use after free in Windows BitLocker allows an authorized attacker to elevate privileges locally.

Use after free in Windows BitLocker allows an authorized attacker to elevate privileges locally.

Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Hyper-V allows an authorized attacker to elevate privileges locally.

Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Connected Devices Platform Service allows an authorized attacker to deny service locally.

Improper resolution of path equivalence in Windows MapUrlToZone allows an unauthorized attacker to bypass a security feature over a network.

**According to the CVSS metric, the attack vector is network (AV:N), user interaction is required (UI:R), and privileges required are none (PR:N). What does that mean for this vulnerability?** Exploitation of this vulnerability requires an unauthorized attacker to wait for a user to initiate a connection to a malicious server that the attacker has set up prior to the user connecting.
