Unauthenticated service interruption via undisclosed resource mishandling

Published Jul 1, 2026 · Updated Jul 1, 2026

Improper resource release in Delta Electronics DVP80ES3 1.06.00 and earlier allows remote attackers to interrupt PLC service over the network. Delta has not disclosed the resource, request field, protocol operation, or release sequence that the firmware mishandles. Network reachability is sufficient without authentication or user interaction, and the published consequence is limited to availability.
