CVE-2019-19070

Estado: ModificadaAlta (7.5)—

** EN DISPUTA ** Una pérdida de memoria en la función spi_gpio_probe() en el archivo drivers/spi/spi-gpio.c en el kernel de Linux versiones hasta la versión 5.3.11, permite a atacantes causar una denegación de servicio (consumo de memoria) al desencadenar fallos de la función devm_add_action_or_reset(), también se conoce como CID-d3b0ffa1d75d. NOTA: Las partes cuestionan la relevancia de esto porque el sistema ya debe haberse quedado sin memoria antes de que comenzara la sonda.
