CVE-2026-64204
Memory corruption in NI LabVIEW allows code execution via crafted VI
Is CVE-2026-64204 being exploited?
Not confirmed. CVE-2026-64204 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.

How severe is CVE-2026-64204?
CVE-2026-64204 is rated High with a CVSS score of 8.5. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

What should I do about CVE-2026-64204?
Apply vendor update when available; block untrusted VIs and run LabVIEW with least privilege
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Arbitrary code execution or information disclosure when a user opens a crafted VI; attacker runs code with the user's privileges.
Patch when possible
- affected< 23.0.0
- affected>= 23.1.0 and < 23.3.10
- affected>= 24.1.0 and < 24.3.7
- affected>= 25.1.0 and < 25.3.5
- affected>= 26.1.0 and < 26.3.1
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
