CVE-2025-64462 is an out-of-bounds read vulnerability classified under CWE-125 found in National Instruments (NI) LabVIEW software, specifically within the LVResFile::RGetMemFileHandle() function. This vulnerability arises when LabVIEW parses a corrupted VI (Virtual Instrument) file, leading to reading memory outside the intended buffer boundaries. Such out-of-bounds reads can cause the application to disclose sensitive information or, more critically, enable arbitrary code execution by manipulating memory contents. The vulnerability affects NI LabVIEW versions up to 25.3 (2025 Q3) and prior, including versions 0, 23.1.0, 24.1.0, and 25.1.0. Exploitation requires an attacker to convince a user to open a specially crafted VI file, which means user interaction is necessary. The CVSS v3.1 score of 7.8 reflects a high severity, with an attack vector of local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but user interaction required (UI:R). The scope is unchanged (S:U), and the impact is high on confidentiality, integrity, and availability (C:H/I:H/A:H). No public exploits have been reported yet, but the potential for severe damage exists, especially in environments where LabVIEW is used for critical industrial control, automation, or research applications. The vulnerability underscores the risks of processing untrusted or malformed VI files and highlights the need for secure file handling and patch management.

For European organizations, the impact of CVE-2025-64462 can be significant, particularly in sectors relying heavily on NI LabVIEW for automation, industrial control, and scientific research. Successful exploitation could lead to unauthorized disclosure of sensitive intellectual property or operational data, disruption of critical processes through arbitrary code execution, and potential compromise of safety systems. This could result in financial losses, reputational damage, regulatory penalties under GDPR if personal data is exposed, and operational downtime. The requirement for user interaction means social engineering or phishing campaigns could be leveraged to deliver malicious VI files. Given the widespread use of LabVIEW in engineering firms, manufacturing plants, and research institutions across Europe, the threat could affect a broad range of organizations, particularly those involved in high-tech manufacturing, automotive, aerospace, and energy sectors.

1. Apply official patches from NI as soon as they become available to address this vulnerability. 2. Until patches are released, restrict the opening of VI files to trusted sources only and implement strict file validation and scanning procedures. 3. Educate users about the risks of opening VI files from untrusted or unknown origins to reduce the likelihood of social engineering exploitation. 4. Employ application whitelisting and sandboxing techniques to limit the execution environment of LabVIEW and contain potential exploits. 5. Monitor network and endpoint activity for unusual behavior indicative of exploitation attempts, such as unexpected process launches or memory access violations. 6. Segment networks to isolate critical LabVIEW environments from general user workstations to reduce attack surface. 7. Maintain regular backups of critical VI files and configurations to enable recovery in case of compromise. 8. Collaborate with NI support and subscribe to vulnerability advisories to stay informed about updates and mitigation guidance.
