| Exposure of sensitive information to an unauthorized actor in Windows Shell allows an authorized attacker to perform spoofing over a network. |
| Heap-based buffer overflow in Windows NTFS allows an authorized attacker to execute code locally. |
| Improper access control in Windows Client-Side Caching (CSC) Service allows an authorized attacker to disclose information locally. |
| Absolute path traversal in Windows Shell allows an unauthorized attacker to perform spoofing with a physical attack. |
| Use of a broken or risky cryptographic algorithm in Windows Kerberos allows an authorized attacker to disclose information locally. |
| Time-of-check time-of-use (toctou) race condition in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Out-of-bounds read in Windows Internet Connection Sharing (ICS) allows an unauthorized attacker to disclose information with a physical attack. |
| Protection mechanism failure in Windows Remote Assistance allows an unauthorized attacker to bypass a security feature locally. |
| Exposure of sensitive information to an unauthorized actor in Windows Remote Procedure Call allows an unauthorized attacker to disclose information locally. |
| Heap-based buffer overflow in Windows Common Log File System Driver 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. |
| 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. |
| Improper access control in Windows Deployment Services allows an unauthorized attacker to execute code over an adjacent network. |
| 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.
