Code execution via malformed VI resource parsing
Published Dec 18, 2025 · Updated Dec 18, 2025
Out-of-bounds read in NI LabVIEW 25.3.2 and earlier allows local users to disclose memory or execute code through a crafted VI file. LVResFile::RGetMemFileHandle() reads beyond a memory boundary while parsing corrupted VI resource data; NI has not disclosed the unchecked field or calculation. Exploitation requires a user to open the malicious VI, after which code runs with that user's privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=22.3.6
- Affected versionversion=23.1.0 <=23.3.7
- Affected versionversion=24.1.0 <=24.3.4
- Affected versionversion=25.1.0 <=25.3.2
