CVE-2019-12456

Description

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
