CVE-2026-50254 is a missing-release-of-memory vulnerability in the OFFIS DCMTK Toolkit affecting versions prior to 3.7.0. An unauthenticated remote client can repeatedly open a DICOM association and send an A-ASSOCIATE-RQ containing many Extended Negotiation items followed by a malformed or truncated Extended Negotiation item. This drives an error path that leaks memory instead of releasing parsed data structures. The issue is particularly impactful against storescp in its default single-process mode, where repeated crafted connection requests cause resident memory usage to grow rapidly until the process is killed or otherwise stops accepting DICOM connections. Upstream reporting identifies the fix as commit 23f181f7a.
