National Instruments disclosed two high-severity memory corruption vulnerabilities in NI LabVIEW that can be triggered when a user opens a specially crafted .vi file. CVE-2026-32862 is an out-of-bounds write in ResFileFactory::InitResourceMgr(), and CVE-2026-32863 is an out-of-bounds read in sentry_transaction_context_set_operation(). NI said both flaws can result in information disclosure and may enable arbitrary code execution.
The vulnerabilities affect NI LabVIEW 2026 Q1 (26.1.0) and earlier versions and require user interaction for successful exploitation. The issues are tracked under CWE-787 and CWE-125, respectively, and were published with high-severity CVSS scoring and vendor advisory references from National Instruments, indicating organizations using LabVIEW should prioritize remediation and treat untrusted VI files as potentially malicious.

National Instruments disclosed two high-severity memory corruption vulnerabilities in **NI LabVIEW** that can be exploited when a user opens specially crafted project files. **`CVE-2026-32860`** is an out-of-bounds write flaw (`CWE-787`) triggered while LabVIEW loads a corrupted **`.lvlib`** file, while **`CVE-2026-32864`** is an out-of-bounds read issue (`CWE-125`) in `mgcore_SH_25_3!aligned_free()` that can be triggered through a malicious **VI** file. Both flaws may result in information disclosure or arbitrary code execution.

Several high-severity vulnerabilities have been identified in NI LabVIEW, affecting version 2025 Q3 (25.3) and earlier. These vulnerabilities include out-of-bounds reads and writes, stack-based buffer overflows, and use-after-free conditions in various LabVIEW components such as `LVResFile::FindRsrcListEntry()`, `mgocre_SH_25_3!RevBL()`, `LVResource::DetachResource()`, and `sentry!sentry_span_set_data()`. Exploitation of these flaws requires a user to open a specially crafted VI file, potentially leading to information disclosure or arbitrary code execution. The vulnerabilities are not remotely exploitable but pose significant risk if a malicious file is opened on a vulnerable system. CISA has issued an advisory confirming that these vulnerabilities (CVE-2025-64461 through CVE-2025-64469) impact critical infrastructure sectors, including manufacturing, defense, IT, and transportation. The advisory recommends users update to the latest version of LabVIEW to mitigate these risks. All vulnerabilities have been assigned a CVSS v3 base score of 7.8 or higher, underscoring their severity and the importance of prompt remediation. No evidence of exploitation in the wild has been reported as of the latest advisories.

National Instruments Circuit Design Suite versions 14.3.1 and earlier are affected by two critical memory corruption vulnerabilities, CVE-2025-6033 and CVE-2025-6034. The first vulnerability, CVE-2025-6033, is caused by an out-of-bounds write in the XML_Serialize() function when using the SymbolEditor component. This flaw can result in information disclosure or arbitrary code execution if a user opens a specially crafted .sym file. The second vulnerability, CVE-2025-6034, is due to an out-of-bounds read in the DefaultFontOptions() function, also within the SymbolEditor, and can similarly lead to information disclosure or arbitrary code execution under the same exploitation conditions. Both vulnerabilities require user interaction, specifically opening a malicious .sym file, and are not remotely exploitable without such action. CISA has issued an advisory highlighting that successful exploitation could allow attackers to corrupt memory, potentially leading to the execution of arbitrary code or the disclosure of sensitive information. The vulnerabilities are rated as high severity, with CVSS v4 scores of 8.4 and v3.1 base scores of 7.8, reflecting the significant risk posed to affected systems. The flaws impact sectors such as communications, defense industrial base, and government services, where Circuit Design Suite is commonly deployed. The vulnerabilities stem from improper handling of memory resources, specifically type confusion and out-of-bounds memory access. National Instruments has acknowledged the issues and coordinated disclosure with security researchers and CISA. No evidence suggests that these vulnerabilities are being actively exploited in the wild at this time. Users are advised to avoid opening untrusted .sym files and to apply any available patches or mitigations as soon as they are released. The vulnerabilities highlight the ongoing risks associated with complex file parsing in engineering and design software. Organizations using affected versions should review their security posture and consider additional controls to limit exposure. The advisories recommend monitoring for unusual activity and ensuring that only trusted files are opened within the application. National Instruments has provided contact information for further security guidance and is expected to release updates addressing these vulnerabilities. The disclosure underscores the importance of regular software updates and user awareness in mitigating targeted attacks via crafted files.
