CVE-2026-3650 · Grassroots DICOM Missing release of memory after effective lifetime

This page contains facts from public vulnerability sources. Check the original advisory before updating.

A memory leak exists in the Grassroots DICOM library (GDCM). The bug occurs when parsing malformed DICOM files with non-standard VR types in file meta information. The vulnerability leads to vast memory allocations and resource depletion, triggering a denial-of-service condition. A maliciously crafted file can fill the heap in a single read operation without properly releasing it.
