3DescriptionCVE.org
There is an integer overflow vulnerability resulting in an out-of-bounds write recently discovered in NI LabVIEW. This may result in information disclosure or arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted VI file. This vulnerability affects NI LabVIEW 2026 Q3 and prior versions.
AnalysisAI
Integer overflow leading to out-of-bounds write in NI LabVIEW 2026 Q3 and prior enables information disclosure or arbitrary code execution when a user opens a specially crafted VI file. The attack is file-based and requires social engineering to deliver a malicious Virtual Instrument file to a target, making it a credible threat in engineering, research, and industrial automation environments where VI files are routinely shared. …
