Untrusted Pointer Dereference in NI grpc-device API

Publication date: 2026-06-19

Last updated on: 2026-06-25

Assigner: National Instruments

Description

There is an untrusted pointer dereference vulnerability in the NI grpc-device sideband streaming API that may allow an attacker to cause an arbitrary memory dereference, potentially resulting in remote code execution. Successful exploitation requires an attacker to supply a specially crafted Moniker protobuf message. This affects NI grpc-device 2.17.0 and prior versions.

Attack-Flow Graph

Executive Summary

This vulnerability is an untrusted pointer dereference issue in the sideband streaming API of the NI grpc-device server (version 2.17.0 and earlier). It occurs when an attacker supplies a specially crafted Moniker protobuf message, which causes the system to dereference arbitrary memory. This can lead to remote code execution or denial-of-service conditions.

Impact Analysis

Exploitation of this vulnerability can allow an attacker to execute arbitrary code remotely or cause denial-of-service conditions on the affected system. The attack requires no privileges or user interaction and can be performed over the network, making it highly dangerous. It impacts the confidentiality and integrity of the system but does not affect availability.

Mitigation Strategies

To mitigate the vulnerability in NI grpc-device versions 2.17.0 and earlier, it is strongly recommended to upgrade to NI gRPC Device Server version 2.18.0 or later.

This upgrade addresses the untrusted pointer dereference vulnerability that could allow remote code execution or denial-of-service conditions.

Compliance Impact

The vulnerability impacts the confidentiality and integrity of the vulnerable system by allowing potential remote code execution through an untrusted pointer dereference. Such a compromise of confidentiality and integrity could lead to non-compliance with standards and regulations like GDPR and HIPAA, which require protection of sensitive data and system integrity.

However, the provided information does not explicitly describe the direct effects on compliance with these regulations or any specific compliance requirements.
