CVE-2025-53152
📋 TL;DR
A use-after-free vulnerability in Desktop Windows Manager allows authenticated attackers to execute arbitrary code locally on vulnerable Windows systems. This affects Windows devices where an attacker has valid credentials and can run code with standard user privileges. The vulnerability enables local privilege escalation or system compromise.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with SYSTEM privileges, enabling installation of persistent malware, credential theft, and lateral movement across the network.
Likely Case
Local privilege escalation from standard user to SYSTEM/administrator privileges, allowing attackers to bypass security controls and install additional payloads.
If Mitigated
Limited impact if proper endpoint protection, application control, and least privilege principles are enforced, though local privilege escalation remains possible.
🎯 Exploit Status
Exploitation requires authenticated access and understanding of Windows graphics subsystem internals. No public exploit code available at this time.
