CVE-2026-9143: CWE-681 Incorrect conversion between numeric types in NI grpc-device
CVE-2026-9143 is a vulnerability in NI grpc-device versions prior to 2.17.1 involving incorrect conversion between numeric types due to missing range checks in CodeGen. This flaw may cause silent discarding of high bits if a size value exceeds the target type's range. The issue has a low severity rating and does not impact confidentiality or availability but may affect integrity. No official patch or remediation guidance is currently confirmed from the vendor.
AI Analysis
Technical Summary
This vulnerability in NI grpc-device arises from improper numeric type conversion caused by absent range checks in the CodeGen component. When a size value exceeds the range of the target numeric type, high bits may be silently discarded, potentially leading to incorrect behavior or data integrity issues. The affected versions are all releases prior to 2.17.1. The CVSS 3.1 base score is 3.7 (low), reflecting a network attack vector with high attack complexity, no privileges required, no user interaction, and limited impact on integrity only. No known exploits or vendor remediation details are currently available.
Potential Impact
The vulnerability may lead to silent data corruption or incorrect processing due to numeric truncation, impacting the integrity of operations within NI grpc-device. There is no impact on confidentiality or availability. The low CVSS score reflects limited potential for exploitation and impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should be aware of the potential integrity issues when handling size values near or exceeding numeric type limits. No specific workaround or temporary fix is documented.
