Technical details

The vulnerability is an integer conversion error (CWE-195: Signed to Unsigned Conversion Error) that results in an out-of-bounds read when LabVIEW processes specially crafted image data within VI files. The flaw exists in the image loading component and requires user interaction—a user must open a malicious VI file for exploitation to occur. Successful exploitation can lead to information disclosure through memory reads or arbitrary code execution. The vulnerability affects LabVIEW 2026 Q3 and earlier versions across multiple release branches (2026, 2025, 2024, 2023, and 2022). Patches are available through NI Package Manager, Software Downloads, or NI Update Service.
