A fix is referenced (a reference tagged "Patch", often a source commit), but no release containing it is confirmed — find the release that contains it; until it is applied, mitigate (WAF / firewall / segmentation).

There is an integer conversion vulnerability resulting in an out-of-bounds read when loading images 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.

CISA SSVC: Track at low or medium mission impact; Track* at high (mission-essential systems).
Action: A fix is referenced, but no release containing it is confirmed. Check the referenced fix and the vendor's advisory for a release that contains it and apply that within your standard update timelines; until then, restrict network exposure of the affected system or apply the vendor's mitigation.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
