**Name of the Vulnerable Software and Affected Versions**
Windows DWM Core Library versions prior to the fixed version
**Description**
The issue is related to an elevation of privilege vulnerability in the Windows DWM Core Library, which can be exploited to allow an attacker to gain system-level privileges. This vulnerability is associated with the indirect bypass of the process check about DWM of NtDCompositionDuplicateHandleToProcess, leading to a kernel arbitrary address write. The vulnerability affects all current versions of Windows, including Windows 10, 11, and server editions. Microsoft has released security updates to patch this vulnerability.
**Recommendations**
For Windows DWM Core Library versions prior to the fixed version, apply the security update released by Microsoft to patch the vulnerability. As a temporary workaround, consider restricting access to the DWM Core Library until the patch is applied. Avoid using the NtDCompositionDuplicateHandleToProcess function in the affected library until the issue is resolved.
