Descriptions

A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system.

Se encontró un fallo de desbordamiento de pila en el kernel de Linux, todas las versiones 3.x.x y versiones 4.x.x anteriores a 4.18.0, en el controlador del chip WiFi de Marvell. La vulnerabilidad permite a un atacante remoto causar un bloqueo del sistema, resultando en una denegación de servicio, o ejecución de código arbitrario. La más grande amenaza con esta vulnerabilidad es con la disponibilidad del sistema. Si se presenta una ejecución de código, el código se ejecutará con los permisos de root. Esto afectará tanto la confidencialidad como la integridad de los archivos en el sistema.
