CVE-2026-3650 is a high-severity memory leak vulnerability in the Grassroots DICOM library (GDCM) version 3.2.2. It occurs when parsing malformed DICOM files containing non-standard VR types in the file meta information. This flaw causes excessive memory allocation without proper release, potentially leading to resource exhaustion and denial-of-service conditions. There are no known exploits in the wild, and no official patch or remediation has been documented yet.

An out-of-bounds write vulnerability exists in the Grassroots DICOM library (GDCM). The issue is triggered during parsing of a malformed DICOM file containing encapsulated PixelData fragments (compressed image data stored as multiple fragments). This vulnerability leads to a segmentation fault caused by an out-of-bounds memory access due to unsigned integer underflow in buffer indexing. It is exploitable via file input, simply opening a crafted malicious DICOM file is sufficient to trigger the crash, resulting in a denial-of-service condition.
