CVE-2026-32861: CWE-787 Out-of-bounds write in NI LabVIEW
CVE-2026-32861 is a high-severity memory corruption vulnerability in NI LabVIEW affecting versions up to 26.1.0. It arises from an out-of-bounds write when loading a corrupted LVCLASS file, potentially allowing information disclosure or arbitrary code execution. Exploitation requires user interaction to open a maliciously crafted . lvclass file. No official patch or remediation guidance is currently provided by the vendor.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-32861) involves an out-of-bounds write in NI LabVIEW when processing a corrupted LVCLASS file. The flaw can lead to memory corruption, enabling an attacker to disclose sensitive information or execute arbitrary code with the privileges of the user opening the file. The affected versions include all releases up to and including 26.1.0. Exploitation requires user interaction, specifically opening a crafted .lvclass file. The CVSS v3.1 score is 7.8, reflecting high impact on confidentiality, integrity, and availability. No patch or official remediation level has been published by NI as of the data provided.
Potential Impact
Successful exploitation can result in full compromise of the affected system's confidentiality, integrity, and availability due to arbitrary code execution or information disclosure. The attack vector requires local user interaction (opening a malicious file), with low attack complexity and no privileges required prior to exploitation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should avoid opening .lvclass files from untrusted or unknown sources to mitigate risk.
