CVE-2025-2632: Out of Bounds Write Vulnerability in NI LabVIEW reading CPU info from cache
Noroxi assessment
Priority: Monitor (action score 34/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
- Someone with local access to the system can trigger it. No account or password is required. No special conditions are required; it is repeatable.
- Fixed version: NI LabVIEW 22.3.4, 23.3.5, 24.3.2.
Low priority for now. Upgrade to NI LabVIEW 22.3.4, 23.3.5, 24.3.2 or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
Out of bounds write vulnerability due to improper bounds checking in NI LabVIEW reading CPU info from cache 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 2025 Q1 and prior versions.
