How the CVE Works
CVE-2025-24074 is a local privilege escalation vulnerability in the Windows Desktop Window Manager (DWM) Core Library due to improper input validation. An attacker with low privileges can exploit this flaw by sending specially crafted input to the DWM process, triggering a memory corruption condition. This allows arbitrary code execution in the context of SYSTEM, granting full system control. The exploit involves manipulating window messaging structures to bypass security checks, leveraging a race condition or buffer overflow in the DWM rendering pipeline.
