CVE-2026-116488
NXP MCUXpresso SDK USB Middleware before 2.13.0 Heap Overflow via Host Class Drivers
Description

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.
