Lifecycle Timeline
5DescriptionCVE.org
There is a NULL pointer dereference vulnerability in NI grpc-device in the data moniker service that may allow an attacker to cause a denial of service by triggering a crash. Successful exploitation requires an attacker to provide an unknown value to the data moniker service. This affects NI grpc-device 2.17.0 and prior versions.
AnalysisAI
Denial of service in NI grpc-device 2.17.0 and prior allows remote unauthenticated attackers to crash the data moniker service by submitting an unknown value that triggers a NULL pointer dereference. The flaw also impacts deployments embedding the server via NI InstrumentStudio. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must have network reachability to the NI grpc-device server's gRPC listener and must send a request to the data moniker service containing a moniker value that is not registered on the target server; no authentication, user interaction, or non-default configuration is required, because grpc-device exposes the moniker service as part of its normal data-streaming API. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are largely consistent and point to a real but bounded availability risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with network access to the grpc-device gRPC port opens a connection to the data moniker service and issues a request referencing an arbitrary moniker name that has not been registered. The server dereferences a NULL lookup result and the process crashes, taking down all instrument control sessions multiplexed through that server; the attacker can repeat the request after each restart to sustain the outage. … |
| Remediation | Patch available per vendor advisory: upgrade NI grpc-device to the fixed release published in GHSA-7vg9-5c74-289x (https://github.com/ni/grpc-device/security/advisories/GHSA-7vg9-5c74-289x) and apply the corresponding NI InstrumentStudio update referenced in the NI security bulletin (https://www.ni.com/en/support/security/available-critical-and-security-updates-for-ni-software/2026/multiple-vulnerabilities-in-ni-grpc-device-server.html); the specific patched version string is not enumerated in the provided data, so confirm the exact build from those advisories before deployment. … Detailed patch versions, workarounds, and compensating controls in full report. |
