CVE-2026-118785NXP MCUXpresso SDK improper input validation

Low priorityMedium6.7EPSS not scored yet

CVE-2026-118785 is a improper input validation in NXP MCUXpresso SDK, rated medium (6.7 on CVSS 3.1).

Why this priority: Medium severity, with no exploitation signal.

Published · Updated · NVD status: Received

What it is

The software trusts input it should check, so crafted values reach code that assumes they are well formed.

How it is reached

An attacker can exploit it by someone who can already run code or sign in on the machine, without an account, and nobody has to click anything. Success also depends on conditions the attacker does not fully control.

What an attacker gains

A successful attack can read the data it protects and take it offline. In practice, this kind of flaw lets an attacker drive the component into behaviour its authors did not intend.

Is it being exploited?

There is no public report of exploitation yet.

What to do

  1. Upgrade NXP MCUXpresso SDK to a fixed version for your release line (26.09.00, 26.06.01-lts).
  2. Limit who can run code or sign in on the hosts that run it.

Description from NVD

Improper handling of non-secure-world input in NSC veneer functions of NXP MCUXpresso SDK TrustZone-M examples (trustzone_examples), affecting versions through 26.06.00-lts and 26.09.00-pvw2, may allow a non-secure caller to supply unvalidated pointers or untrusted data, causing a timing side-channel, TOCTOU condition, or format-string misuse, potentially resulting in secure-world memory disclosure or denial of service. All software versions starting from 26.06.01-lts and 26.09.00 have fixed this issue.

What this means for your architecture.

A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.

Components it touches

  • Interfaces that accept external input. The flaw sits at the input boundary of the affected component.

Trust boundaries in play

  • Host boundary. The attacker needs a foothold on the machine first; the flaw turns a small foothold into a bigger one.
  • At the input boundary of the affected component. An attacker who crosses it can drive the component into behaviour its authors did not intend.

Questions to answer about your own systems

  • Where does NXP MCUXpresso SDK run in your systems, and at which version?
  • Which of those hosts also run code or users you do not fully trust?
  • What can it reach once compromised: which data stores, secrets and services?
