CVE-2025-55234: Windows SMB Elevation of Privilege Vulnerability

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.
