CVE-2026-16234
Memory corruption in NI LabVIEW allows code execution when opening a malicious VI.
Is CVE-2026-16234 being exploited?
Not confirmed. CVE-2026-16234 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 0.13% probability of exploitation in the next 30 days.
How severe is CVE-2026-16234?
CVE-2026-16234 is rated High. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-16234?

What should I do about CVE-2026-16234?
Do not open untrusted VIs; block/whitelist VI sources; apply vendor patch when released.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Arbitrary code execution or information disclosure if a user opens a crafted VI; attacker can run code with user privileges and exfiltrate data.

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.
