CVE-2026-10647

The CVE concerns the USB CDC-NCM driver (subsys/usb/device_next/class/usbd_cdc_ncm.c) in Zephyr. The code ignores the return value of usbd_ep_enqueue() in cdc_ncm_send(); when enqueue fails, it still calls k_sem_take(&data-sync_sem, K_FOREVER), waiting on a completion that is only signaled from t...
