Who should care

Organizations using National Instruments Circuit Design Suite, especially in industrial or OT environments, and teams that open or process SYM files from outside trusted sources. Security and engineering teams responsible for patching NI software should prioritize this issue.

Technical summary

The advisory describes an out-of-bounds read vulnerability in InternalDraw() in National Instruments Circuit Design Suite. The affected product scope is National Instruments Circuit Design Suite <= 14.3.0. Exploitation requires user interaction: an attacker must trick a user into opening a specially crafted SYM file. The documented impact includes possible information disclosure and, according to the advisory, potential arbitrary code execution.

Defensive priority

High. The issue is rated CVSS 7.8 (HIGH) and is user-assisted, but the affected software is vendor-supported and a fixed version is available. Prioritize patching to reduce exposure to malicious SYM files.

Recommended defensive actions

  • Update National Instruments Circuit Design Suite to 14.3.1 or later.
  • Restrict or scrutinize untrusted SYM files before opening them.
  • Use standard user awareness and file-handling controls to reduce the chance of opening crafted files.
  • Track affected systems running Circuit Design Suite <= 14.3.0 and verify remediation has been applied.

Evidence notes

Source corpus states the vulnerability is an out-of-bounds read in InternalDraw() caused by improper input validation. The advisory identifies the affected product as National Instruments Circuit Design Suite <= 14.3.0 and says exploitation requires a user to open a specially crafted SYM file. National Instruments remediation guidance in the corpus recommends version 14.3.1 or later. CISA published the CSAF advisory on 2025-05-20 with initial revision history entry 'Initial Publication'.
