Descriptions
The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function.
La función sg_ioctl en drivers/scsi/sg.c en el kernel de Linux hasta la versión 4.10.4 permite a usuarios locales provocar una denegación de servicio (desbordamiento de búfer basado en pila) o posiblemente tener otro impacto no especificado a través de un gran tamaño de comando en una llamada SG_NEXT_CMD_LEN ioctl, conduciendo a acceso de escritura fuera de límites en la función sg_write.
