4DescriptionCVE.org
There is a memory corruption vulnerability recently discovered in NI LabVIEW that may result in information disclosure or arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted VI. This vulnerability affects NI LabVIEW 2026 Q3 (26.3.0) and prior versions.
AnalysisAI
Memory corruption in NI LabVIEW 2026 Q3 (26.3.0) and all prior versions enables information disclosure or arbitrary code execution when a victim opens a specially crafted VI (Virtual Instrument) file. The root cause is CWE-787 (Out-of-bounds Write), indicating a write operation beyond the bounds of an allocated buffer during VI file parsing. …

Vulnerability AssessmentAI
| Exploitation | Exploitation has one hard prerequisite: the victim must open a specially crafted VI file in an affected version of NI LabVIEW (26.3.0 or earlier). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 8.5 (High) reflects high impact across confidentiality, integrity, and availability on the vulnerable system, tempered by a local attack vector (AV:L) and mandatory user interaction (UI:P). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Consult the NI security advisory at https://www.ni.com/en/support/security/available-critical-and-security-updates-for-ni-software/2026/memory-corruption-vulnerabilities-ni-labview.html for the specific patched release; the exact fixed version is not independently confirmed from the available intelligence beyond the affected ceiling of 26.3.0. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all LabVIEW 2026 Q3 (26.3.0) and earlier installations across your organization and alert users to refuse VI files from untrusted external sources. …
