CVE-2025-14234 is a buffer overflow vulnerability in CPCA list processing affecting multiple Canon small office multifunction printers and laser printers running firmware version 06.02 and earlier across certain regional product lines. Available technical reporting also describes the issue on Canon imageCLASS MF654Cdw as a heap-based buffer overflow in the CADM service, reachable over the network, where a crafted font embedded in a PJCC request can trigger memory corruption. Successful exploitation may cause the device to become unresponsive or permit arbitrary code execution in the context of the printer.
