CVE-2025-39893

In the Linux kernel, the following vulnerability has been resolved: spi: spi-qpic-snand: unregister ECC engine on probe error and device remove The on-host hardware ECC engine remains registered both when the spi_register_controller() function returns with an error and also on device removal. Change the qcom_spi_probe() function to unregister the engine on the error path, and add the missing unregistering call to qcom_spi_remove() to avoid possible use-after-free issues.

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: spi: spi-qpic-snand: anular el registro del motor ECC en error de sondeo y eliminación de dispositivo El motor ECC de hardware en el host permanece registrado tanto cuando la función spi_register_controller() devuelve un error como en la eliminación del dispositivo. Cambiar la función qcom_spi_probe() para anular el registro del motor en la ruta de error, y añadir la llamada de anulación de registro faltante a qcom_spi_remove() para evitar posibles problemas de uso después de liberación.
