CVE-2025-14233

Code execution via CPCA file-deletion invalid free

Published Jan 15, 2026 · Updated Jan 15, 2026

Invalid free in Canon printer firmware 06.02 and earlier allows remote attackers to execute code or crash devices over the local network. The BJNP service mishandles user-supplied CPCA file-deletion data and releases an invalid pointer, corrupting device memory. No authentication or user interaction is required; the printer must be network-reachable, and exploitation yields device-context code execution or an unresponsive printer.
