Monitor NI advisories; apply patch when released; avoid opening unknown VI files
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Info disclosure and possible arbitrary code execution via out-of-bounds read; attacker must entice user to open crafted VI.

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.
