CVE-2025-11772

SYSTEM code execution via co-installer DLL hijacking

Published Dec 1, 2025 · Updated Dec 1, 2025

Privilege escalation in Synaptics Fingerprint Driver allows local users to execute arbitrary code as SYSTEM during driver installation. CheckFPDatabase.exe runs elevated from the low-privileged-user-writable C:\ProgramData\Synaptics directory and loads required system DLLs through the default search path. Exploitation requires local access to plant a same-named DLL before a fingerprint-driver installation invokes the co-installer.
