CVE-2025-64086Public exploitNetwork attack vector

Application crash via uninitialized file-stream dereference

Published Dec 9, 2025 · Updated Dec 11, 2025

NULL pointer dereference in PDF-XChange Editor 10.7.3.401 allows context-dependent attackers to crash the application via a crafted PDF. The util.readFileIntoStream method leaves a file-stream object zeroed when stream creation fails, then dereferences that uninitialized object. A user must open the malicious PDF; exploitation terminates the editor without reported data disclosure or modification.
