CVE-2025-64467 is an out-of-bounds read vulnerability classified under CWE-125 found in the National Instruments (NI) LabVIEW software, specifically within the LVResFile::FindRsrcListEntry() function. This function is responsible for parsing resource list entries in VI (Virtual Instrument) files. When a corrupted or specially crafted VI file is processed, the function may read memory outside the intended buffer bounds, leading to undefined behavior. This can result in information disclosure, where sensitive memory contents may be leaked, or arbitrary code execution, where an attacker could execute malicious code within the context of the LabVIEW process. Exploitation requires that an attacker convince a user to open a malicious VI file, making user interaction necessary. The vulnerability affects multiple versions of NI LabVIEW, including 23.1.0, 24.1.0, 25.1.0, and all versions up to 25.3 (2025 Q3). The CVSS v3.1 base score is 7.8, indicating high severity due to high impact on confidentiality, integrity, and availability, combined with low attack complexity and no privileges required. No public patches or known exploits have been reported at the time of publication, but the vulnerability poses significant risk given LabVIEW's use in critical industrial and scientific environments.

The potential impact of CVE-2025-64467 is substantial for organizations relying on NI LabVIEW for industrial automation, scientific research, and engineering development. Successful exploitation could lead to unauthorized disclosure of sensitive information, including intellectual property or operational data, which could be leveraged for further attacks or industrial espionage. More critically, arbitrary code execution could allow attackers to execute malicious payloads, potentially leading to system compromise, disruption of industrial control processes, or sabotage. Given LabVIEW's integration in critical infrastructure and manufacturing environments, such compromises could result in operational downtime, safety hazards, and financial losses. The requirement for user interaction limits remote exploitation but does not eliminate risk, especially in environments where VI files are shared or imported from external sources. The absence of known exploits currently reduces immediate threat but does not preclude future active exploitation. Organizations worldwide using affected LabVIEW versions face risks to confidentiality, integrity, and availability of their systems and data.

To mitigate CVE-2025-64467, organizations should: 1) Immediately update NI LabVIEW to the latest version once a patch is released by the vendor, as no official patch is currently available. 2) Implement strict controls on the handling and opening of VI files, including restricting file sources to trusted origins and scanning files for anomalies before use. 3) Employ application whitelisting and sandboxing techniques to limit the execution context of LabVIEW and reduce the impact of potential code execution. 4) Educate users about the risks of opening untrusted VI files and enforce policies to minimize user interaction with potentially malicious files. 5) Monitor LabVIEW environments for unusual behavior or indicators of compromise, including unexpected process activity or memory anomalies. 6) Consider network segmentation to isolate LabVIEW systems from critical infrastructure to contain potential breaches. 7) Use endpoint detection and response (EDR) tools to detect exploitation attempts and respond promptly. These measures, combined with vendor patching, will reduce the risk and impact of this vulnerability.
