Descriptions

An issue was discovered in the MPT3COMMAND case in _ctl_ioctl_main in drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel through 5.1.5. It allows local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a "double fetch" vulnerability. NOTE: a third party reports that this is unexploitable because the doubly fetched value is not used

** EN DISPUTA ** Se detecto un problema en MPT3COMMAND case en _ctl_ioctl_main en drivers/scsi/mpt3sas/mpt3sas_ctl.c en el kernel de Linux hasta la versión 5.1.5. Permite a los usuarios locales generar una Denegación de Servicio o posiblemente tener otro impacto no especificado al cambiar el valor de ioc_number entre dos lecturas del kernel de este valor, también conocida como una vulnerabilidad de "double fetch".
