How the CVE Works
CVE-2025-24060 is a local privilege escalation vulnerability in the Windows Desktop Window Manager (DWM) Core Library due to improper input validation. An attacker with low-level privileges can exploit this flaw by sending specially crafted input to the DWM process, triggering a memory corruption or logic flaw. This allows the attacker to execute arbitrary code with elevated SYSTEM privileges. The exploit leverages a race condition or buffer overflow in the DWM’s handling of window management messages, bypassing security checks. Successful exploitation grants full system control without requiring user interaction.
