CVE-2025-30418 National Instruments CVE debrief

CVE-2025-30418 is a high-severity memory-corruption issue in National Instruments Circuit Design Suite. According to the CISA CSAF advisory, improper input validation in CheckPins() can cause an out-of-bounds write, and exploitation requires a user to open a specially crafted SYM file. The vendor advises updating to version 14.3.1 or later.

Who should care

Teams running National Instruments Circuit Design Suite version 14.3.0 or earlier should care first, especially engineering workstations and industrial/OT environments where SYM files may be exchanged or opened routinely. Security teams responsible for endpoint patching, application allowlisting, and file-ingress controls should also prioritize this issue.

Technical summary

The advisory describes an out-of-bounds write in CheckPins() caused by improper input validation. The affected product range is National Instruments Circuit Design Suite <=14.3.0. The published CVSS v3.1 vector is AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, reflecting that successful exploitation depends on user interaction but can still lead to arbitrary code execution impacts. The source advisory recommends updating to 14.3.1 or later.

Defensive priority

High. Patch promptly because the flaw can lead to arbitrary code execution, even though exploitation requires opening a crafted SYM file. Prioritize systems that handle untrusted or externally supplied design files.

Recommended defensive actions

  • Update National Instruments Circuit Design Suite to version 14.3.1 or later.
  • Inventory systems running Circuit Design Suite 14.3.0 and earlier so they can be patched first.
  • Treat SYM files from untrusted or external sources as suspicious and restrict where they can be opened.
  • Use standard ICS defense-in-depth controls such as least privilege, application control, and segregated engineering workstations.
  • Monitor vendor and CISA advisories for any follow-on guidance or updates.

Evidence notes

Primary evidence comes from the CISA CSAF advisory ICSA-25-140-02, published and modified on 2025-05-20. The advisory identifies the affected product as National Instruments Circuit Design Suite <=14.3.0, describes the CheckPins() out-of-bounds write, and lists the recommended fix as version 14.3.1 or later. The provided CVSS vector is AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. No KEV listing was provided in the supplied corpus.
