| 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. |
