Does this matter?

Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.

Description

There is an incorrect conversion between numeric types vulnerability in NI grpc-device due to missing range checks in CodeGen. This may silently discard high bits if a size value exceeded the target type's range. This affects NI grpc-device 2.17.0 and prior versions.
