CVSS v3.1 |
| 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. |
| Exposure of sensitive information to an unauthorized actor in Windows File Explorer allows an unauthorized attacker to perform spoofing over a network. |
| This vulnerability is caused by a CWE‑159: "Improper Handling of Invalid Use of Special Elements" weakness, which leads to an unrecoverable inconsistency in the CLFS.sys driver. This condition forces a call to the KeBugCheckEx function, allowing an unprivileged user to trigger a system crash. Microsoft silently fixed this vulnerability in the September 2025 cumulative update for Windows 11 2024 LTSC and Windows Server 2025. Windows 25H2 (released in September) was released with the patch. Windows 1123h2 and earlier versions remain vulnerable. |

| Insertion of sensitive information into log file in Windows NTFS allows an unauthorized attacker to disclose information with a physical attack. |
| Integer overflow or wraparound in Windows Fast FAT Driver allows an unauthorized attacker to execute code locally. |
| Out-of-bounds read in Windows NTFS allows an authorized attacker to disclose information locally. |
| Heap-based buffer overflow in Windows NTFS allows an unauthorized attacker to execute code locally. |
| Improper neutralization in Microsoft Management Console allows an unauthorized attacker to bypass a security feature locally. |
