There is an unchecked enum cast vulnerability in NI grpc-device BeginSidebandStream that may allow an attacker to trigger invalid enum states and undefined behavior, potentially resulting in a denial of service. Successful exploitation requires an attacker to supply a specially crafted message containing an out-of-range value. This affects NI grpc-device 2.17.0 and prior versions.
