Code execution via XML_Serialize out-of-bounds write
Published Sep 30, 2025 · Updated Sep 30, 2025
Out-of-bounds write in NI Circuit Design Suite 14.3.1 and earlier allows attackers to execute code via a crafted .sym file. Symbol Editor's XML_Serialize() writes outside a memory buffer while processing attacker-controlled data from the file. Exploitation requires a user to open the file; successful corruption enables information disclosure or code execution in that user's context.

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.
