| Heap-based buffer overflow in Windows DWM Core Library allows an authorized attacker to elevate privileges locally. |
| Heap-based buffer overflow in Windows DWM Core Library allows an authorized attacker to elevate privileges locally. |
| Improper neutralization of special elements used in a command ('command injection') in Windows PowerShell allows an unauthorized attacker to execute code locally. |
| Use after free in Windows Cloud Files Mini Filter Driver allows an authorized attacker to elevate privileges locally. |
| 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. |
| 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.
