  - SMB Server might be susceptible to relay attacks depending on the configuration. An attacker who     successfully exploited these vulnerabilities could perform relay attacks and make the users subject to     elevation of privilege attacks. The SMB Server already supports mechanisms for hardening against relay     attacks: SMB Server signing SMB Server Extended Protection for Authentication (EPA) Microsoft is releasing     this CVE to provide customers with audit capabilities to help them to assess their environment and to     identify any potential device or software incompatibility issues before deploying SMB Server hardening     measures that protect against relay attacks. If you have not already enabled SMB Server hardening     measures, we advise customers to take the following actions to be protected from these relay attacks:
    Assess your environment by utilizing the audit capabilities that we are exposing in the September 2025     security updates. See Support for Audit Events to deploy SMB Server HardeningSMB Server Signing & SMB     Server EPA. Adopt appropriate SMB Server hardening measures. (CVE-2025-55234)

  - Improper restriction of communication channel to intended endpoints in Windows PowerShell allows an     authorized attacker to elevate privileges locally. (CVE-2025-49734)
