| Improper handling of insufficient permissions or privileges in Windows Error Reporting allows an authorized attacker to elevate privileges locally. |
| Time-of-check time-of-use (toctou) race condition in Windows Installer allows an authorized attacker to elevate privileges locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Graphics Kernel allows an authorized attacker to elevate privileges locally. |
| Improper input validation in Windows LDAP - Lightweight Directory Access Protocol allows an authorized attacker to perform tampering over a network. |
| Free of memory not on the heap in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Time-of-check time-of-use (toctou) race condition in Windows Kernel Memory allows an authorized attacker to elevate privileges locally. |
| Exposure of sensitive information to an unauthorized actor in Desktop Windows Manager allows an authorized attacker to disclose information locally. |
| Incorrect privilege assignment in Windows Hello allows an unauthorized attacker to perform tampering locally. |
| Windows Secure Boot stores Microsoft certificates in the UEFI KEK and DB. These original certificates are approaching expiration, and devices containing affected certificate versions must update them to maintain Secure Boot functionality and avoid compromising security by losing security fixes related to Windows boot manager or Secure Boot.
The operating system’s certificate update protection mechanism relies on firmware components that might contain defects, which can cause certificate trust updates to fail or behave unpredictably. This leads to potential disruption of the Secure Boot trust chain and requires careful validation and deployment to restore intended security guarantees.

| Use of uninitialized resource in Dynamic Root of Trust for Measurement (DRTM) allows an authorized attacker to disclose information locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Bluetooth Service allows an authorized attacker to elevate privileges locally. |
| 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 Hardening—SMB Server Signing & SMB Server EPA.
Adopt appropriate SMB Server hardening measures. |
