CVE-2025-15359Network attack vector

Unauthenticated memory corruption

Published Dec 30, 2025 · Updated Dec 30, 2025

An out-of-bounds write in Delta Electronics DVP-12SE11T before 2.16 allows remote attackers to corrupt device memory via network traffic. Delta has not disclosed the affected firmware routine, the malformed field, or the bounds-checking failure that permits the write. Network access to the PLC is sufficient without authentication or user interaction, and successful exploitation can alter device operation or interrupt service.
