CVE-2026-116488 PUBLISHED

NXP MCUXpresso SDK USB Middleware before 2.13.0 Heap Overflow via Host Class Drivers

Assigner: VulnCheck
Reserved: 26.10.2026 Published: 26.10.2026 Updated: 26.10.2026

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.
