CVE-2025-14235 is an out-of-bounds write vulnerability affecting multiple Canon small office multifunction printers and laser printers running firmware version 06.02 and earlier. The flaw is in XPS font fpgm data processing, and reporting also describes the issue as occurring during TrueType font parsing. Improper validation of user-supplied font data can cause a write past the end of an allocated object while the device processes crafted XPS content, leading to a buffer overflow. The vulnerability affects multiple Canon product families sold in Japan, the United States, and Europe, including Satera, imageCLASS, i-SENSYS, and imageRUNNER lines.
