Descriptions

drivers/net/can/usb/gs_usb.c in the Linux kernel 4.9.x and 4.10.x before 4.10.2 interacts incorrectly with the CONFIG_VMAP_STACK option, which allows local users to cause a denial of service (system crash or memory corruption) or possibly have unspecified other impact by leveraging use of more than one virtual page for a DMA scatterlist.

drivers/net/can/usb/gs_usb.c en el kernel de Linux 4.9.x y 4.10.x en versiones anteriores a 4.10.2 interactúa incorrectamente con la opción CONFIG_VMAP_STACK, que permite a usuarios locales provocar una denegación de servicio (bloqueo del sistema o corrupción de memoria) o posiblemente tiene otro impacto no especificado aprovechando el uso de más de una página virtual para la lista de dispersión DMA.
