Remote server crash via unknown moniker value

Published Jun 19, 2026 · Updated Jun 19, 2026

NULL pointer dereference in NI grpc-device 2.17.0 and earlier allows remote attackers to crash the server via the data moniker service. The service accepts an unknown moniker value and reaches a NULL pointer dereference; NI has not disclosed the affected function or validation gap. No privileges or user interaction are required, and InstrumentStudio 26.3.0 and earlier is also affected; the reported consequence is a server crash only.
