CVE-2025-14233 is an invalid free vulnerability in the CPCA file deletion processing component affecting Small Office Multifunction Printers and Laser Printers from Canon. The issue impacts firmware version v06.02 and earlier on models including Satera LBP670C Series/Satera MF750C Series sold in Japan; Color imageCLASS LBP630C/Color imageCLASS MF650C Series/imageCLASS LBP230 Series/imageCLASS X LBP1238 II/imageCLASS MF450 Series/imageCLASS X MF1238 II/imageCLASS X MF1643i II/imageCLASS X MF1643iF II sold in the US; and i-SENSYS LBP630C Series/i-SENSYS MF650C Series/i-SENSYS LBP230 Series/1238P II/1238Pr II/i-SENSYS MF450 Series/i-SENSYS MF550 Series/1238i II/1238iF II/imageRUNNER 1643i II/imageRUNNER 1643iF II sold in Europe.
An unauthenticated attacker on the same network segment can exploit this vulnerability remotely with low complexity to cause the affected printer to become unresponsive (denial of service) or execute arbitrary code. The CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) reflects its critical severity, high impact on confidentiality, integrity, and availability, and lack of prerequisites.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation directly exercises deallocation paths and can find incorrect release calls or mismatched alloc/free pairs.
Documented development standards and tools can mandate safe memory-management idioms and static checks that avoid invalid releases.
An SDLC that incorporates security can embed memory-safety requirements, reducing the chance such coding errors are introduced.
Engineering principles require correct resource management and memory-release patterns that stop invalid pointer releases from being coded.
