| Generation of error message containing sensitive information in Windows Kernel allows an authorized attacker to disclose information locally. |
| Heap-based buffer overflow in Windows Media allows an unauthorized attacker to execute code locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Graphics Kernel allows an authorized attacker to elevate privileges locally. |
| Out-of-bounds read in Capability Access Management Service (camsvc) 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. |
| Windows Remote Procedure Call Interface Definition Language (IDL) Elevation of Privilege Vulnerability |
| 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 TPM allows an authorized attacker to disclose information locally. |
| Out-of-bounds read in Windows Internet Connection Sharing (ICS) allows an unauthorized attacker to disclose information with a physical attack. |
| Exposure of sensitive information to an unauthorized actor in Tablet Windows User Interface (TWINUI) Subsystem allows an authorized attacker to disclose information locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Tablet Windows User Interface (TWINUI) Subsystem allows an authorized attacker to elevate privileges locally. |
| Improper access control in Windows Hyper-V allows an authorized attacker to disclose information locally. |
| Protection mechanism failure in Windows Remote Assistance allows an unauthorized attacker to bypass a security feature locally. |
| Heap-based buffer overflow in Windows Common Log File System Driver allows an authorized attacker to elevate privileges locally. |
| Insertion of sensitive information into log file in Windows Kernel allows an unauthorized attacker to disclose information locally. |
| 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. |
| 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.
