CVE-2026-17264Network attack vector

Application crash via JPEG pixel-data heap overwrite

Published Aug 6, 2026 · Updated Aug 7, 2026

Out-of-bounds write in Medixant RadiAnt DICOM Viewer 2025.2 and earlier allows remote attackers to crash the application via a crafted DICOM file. The JPEG-compressed pixel-data path writes attacker-controlled data beyond a heap buffer, although the affected function and failed bounds check are undisclosed. A user must open the file, and the demonstrated consequence is limited to an application crash rather than data disclosure or modification.
