3Description
There is a memory corruption vulnerability due to an out-of-bounds write when loading a corrupted LVCLASS file in NI LabVIEW. This vulnerability may result in information disclosure or arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted .lvclass file. This vulnerability affects NI LabVIEW 2026 Q1 (26.1.0) and prior versions.
Analysis
Memory corruption via out-of-bounds write in NI LabVIEW allows arbitrary code execution and information disclosure when processing maliciously crafted .lvclass files. Affects LabVIEW 2026 Q1 (26.1.0) and all prior versions. …
