CVE-2026-32861: CWE-787 Out-of-bounds write in NI LabVIEW
There is a memory corruption vulnerability due to an out-of-bounds write when loading a corrupted LVCLASS file in NI LabVIEW. This vulnerability may result in information disclosure or arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted .lvclass file. This vulnerability affects NI LabVIEW 2026 Q1 (26.1.0) and prior versions.
AI Analysis
Technical Summary
This vulnerability (CWE-787) involves an out-of-bounds write in NI LabVIEW when processing corrupted LVCLASS files. The flaw allows an attacker to cause memory corruption that may result in disclosure of sensitive information or execution of arbitrary code. It affects NI LabVIEW versions 0 through 26.1.0. The CVSS 3.1 base score is 7.8, indicating high severity, with attack vector local, low attack complexity, no privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation can lead to full compromise of the affected system by enabling arbitrary code execution or unauthorized information disclosure. The attack requires a user to open a malicious LVCLASS file, making social engineering a necessary component. The vulnerability affects confidentiality, integrity, and availability of the system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time. Until a patch is available, users should avoid opening LVCLASS files from untrusted sources to mitigate risk.
