CVE-2025-59301

Service interruption via malformed Modbus/TCP packets

Published Dec 22, 2025 · Updated Dec 22, 2025

Improper input validation in Delta Electronics DVP15MC11T before 1.16.0 allows attackers to interrupt service via Modbus/TCP packets. The Modbus/TCP packet-processing path accepts insufficiently validated packet content, but Delta has not disclosed the affected field or exact failure mode. Exploitation requires adjacent-network access, high privileges, user interaction, and high-complexity conditions; the bounded result is service interruption.
