Azure RTOS USBX is a USB host, device, and on-the-go (OTG) embedded stack, that is fully integrated with Azure RTOS ThreadX. Prior to version 6.1.12, the USB DFU UPLOAD functionality may be utilized to introduce a buffer overflow resulting in overwrite of memory contents. In particular cases this may allow an attacker to bypass security features or execute arbitrary code. The implementation of ux_device_class_dfu_control_request function prevents buffer overflow during handling of DFU UPLOAD command when current state is UX_SYSTEM_DFU_STATE_DFU_IDLE. This issue has been patched, please upgrade to version 6.1.12. As a workaround, add the UPLOAD_LENGTH check in all possible states.
