cve-2026-17264

This tag covers CVE-2026-17264, a heap out-of-bounds write vulnerability in Medixant RadiAnt DICOM Viewer versions 2025.2 and earlier. Disclosed by CISA, the flaw is triggered by opening a malicious DICOM file with JPEG-compressed pixel data, potentially crashing the application or allowing arbitrary code execution. No public exploitation had been reported as of August 6, 2026. For Windows administrators, the key point is that this is a client-side file-parsing issue, not a network-exposed service. The recommended action is to update RadiAnt DICOM Viewer to version 2026.1 immediately. Discussions emphasize the importance of patching and cautious handling of untrusted DICOM files.
