Technical details
An incorrect conversion between numeric types (CWE-681) exists in the CodeGen component of NI grpc-device. The vulnerability is caused by missing range checks when converting size values between different numeric types, which can lead to high bits being silently discarded if the value exceeds the capacity of the target type. An attacker could potentially exploit this over a network, though it requires high attack complexity. The flaw affects NI grpc-device versions 2.17.0 and prior, as well as InstrumentStudio versions 26.3.0 and prior. Users are advised to upgrade to NI grpc-device 2.18.0 or later.
Affected products
- NI grpc-device <= 2.17.0
- NI InstrumentStudio <= 26.3.0
