CVE-2026-12051

The USB DFU class implementation in Zephyr's new experimental devicenext USB device stack contains a NULL pointer dereference in handledownload subsys/usb/devicenext/class/usbddfu.c. The handler computes MINsetup-wLength, buf-len and passes buf-data to the image write callback without checking th...

CVE-2026-12051

The CVE affects Zephyr’s USB DFU, specifically the device_next USB device stack. In handle_download() the code dereferences buf without verifying buf is NULL during DFU_DNLOAD with no Data OUT stage (zero-length terminate). This NULL pointer dereference on the control endpoint after transitioning...
