Detailsinfo

A vulnerability classified as critical has been found in NI LabVIEW up to 22.3.5/23.3.6/24.3.3/25.2.x. This affects an unknown function. The manipulation of the argument VILinkObj with an unknown input leads to a improper validation of specified index, position, or offset in input vulnerability. CWE is classifying the issue as CWE-1285. The product receives input that is expected to specify an index, position, or offset into an indexable resource such as a buffer or file, but it does not validate or incorrectly validates that the specified index/position/offset has the required properties. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A memory corruption vulnerability due to improper error handling when a VILinkObj is null exists in NI LabVIEW that may result in arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted VI. This vulnerability affects NI LabVIEW 2025 Q1 and prior versions.

The weakness was disclosed by Rocco Calvi. It is possible to read the advisory at ni.com. This vulnerability is uniquely identified as CVE-2025-7849 since 07/18/2025.
