CVE-2018-14734

Estado: ModificadaAlta (7.8)—

drivers/infiniband/core/ucma.c en el kernel de Linux hasta la versión 4.17.11 permite que ucma_leave_multicast acceda a cierta estructura de datos tras un paso de limpieza en ucma_process_join, lo que permite que los atacantes provoquen una denegación de servicio (uso de memoria previamente liberada).
