EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 83% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
