CVE-2026-116488: NXP MCUXpresso SDK USB Middleware Heap Overflow Vulnerability

Sources read

Source agreement

0/2

Evidence confidence

%37

Short explanation

NXP MCUXpresso SDK USB middleware versions prior to 2.13.0 contain a heap buffer overflow vulnerability in host audio, video, and CDC class drivers due to trusted inputs.

Why does it matter?

A malicious USB device can supply crafted descriptors that write past fixed-size arrays, corrupting heap memory to achieve code execution or denial of service.

What should be done?

Update mcuxsdk-middleware-usb to version 2.13.0 or later
Apply the provided patch commits
Follow vendor security advisories

Show the technical text from the sources

NXP MCUXpresso SDK USB middleware (mcuxsdk-middleware-usb) before 2.13.0 contains a heap buffer overflow in host audio, video and CDC class drivers that trust device-supplied bNumEndpoints and bLength values. A malicious USB device can supply crafted descriptors that write endpoint entries past the fixed-size epList array, corrupting heap memory for code execution or denial of service.
