How the CVE Works:
CVE-2025-24062 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 or logic flaw. This allows the attacker to execute arbitrary code with elevated SYSTEM privileges, bypassing security restrictions. The exploit leverages the DWM’s failure to validate user-supplied data before processing, leading to unauthorized access to kernel-level operations.
