CVE-2026-64242
Full vulnerability record from the local CVENow database.
Description
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: net2280: Fix double free in probe error path usb_initialize_gadget() installs gadget_release() as the release callback for the embedded gadget device. The struct net2280 instance is therefore released through gadget_release() when the gadget device's last reference is dropped. The probe error path calls net2280_remove(), which tears down the partially initialized device and drops the gadget reference with usb_put_gadget(). Calling kfree(dev) afterwards can free the same object again. Drop the explicit kfree() and let the gadget device release callback handle the final free. This issue was found by a static analysis tool I am developing.

"value": "En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\nusb: gadget: net2280: Corrección de doble liberación en la ruta de error de sondeo\n\nusb_initialize_gadget() instala gadget_release() como la función de devolución de llamada de liberación para el dispositivo gadget incrustado. La instancia de la estructura net2280 es, por lo tanto, liberada a través de gadget_release() cuando se elimina la última referencia del dispositivo gadget.\n\nLa ruta de error de sondeo llama a net2280_remove(), que desmantela el dispositivo parcialmente inicializado y elimina la referencia del gadget con usb_put_gadget(). Llamar a kfree(dev) después puede liberar el mismo objeto de nuevo.\n\nEliminar la llamada explícita a kfree() y dejar que la función de devolución de llamada de liberación del dispositivo gadget maneje la liberación final. Este problema fue encontrado por una herramienta de análisis estático que estoy desarrollando."
