Lifecycle Timeline
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 26.3.0 and all prior versions enables information disclosure or arbitrary code execution when a user opens a specially crafted Virtual Instrument (VI) file. Classified under CWE-125 (Out-of-bounds Read), the flaw's buffer-overflow and RCE tags suggest that the out-of-bounds read condition can, under certain memory layout circumstances, corrupt control-flow data and escalate beyond information disclosure to full code execution. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a victim user open a specially crafted VI file using a vulnerable 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 base score of 8.5 is driven by high vulnerable-system impacts (VC:H/VI:H/VA:H), but two mitigating metric choices substantially limit realistic exposure: AV:L (local attack vector - the crafted VI file must be opened on the victim machine) and UI:P (passive user interaction - the victim must open the file). … 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 | The primary remediation is to apply the patch or updated version identified in NI's 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. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: identify all NI LabVIEW 26.3.0 and earlier deployments and restrict access to VI files only from trusted, internal sources. …
