Technical details
CVE-2026-64201 is an out-of-bounds read vulnerability in the EnQRunQ function within NI LabVIEW. The vulnerability is triggered when a user opens a specially crafted VI file, making the attack vector local with required user interaction. An attacker can exploit this flaw to read arbitrary memory contents, potentially disclosing sensitive information, or in combination with other techniques, to achieve arbitrary code execution with the privileges of the LabVIEW process. Patches are available for LabVIEW 2023 through 2026 via NI Update Service or direct downloads; versions 2022 and prior are out of mainstream support.
