The __mptctl_ioctl function in drivers/message/fusion/mptctl.c in the Linux kernel before 5.4.14 allows local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a "double fetch" vulnerability, aka CID-28d76df18f0a. NOTE: the vendor states "The security impact of this bug is not as bad as it could have been because these operations are all privileged and root already has enormous destructive power."

CVE-2020-12652 kernel: race condition in __mptctl_ioctl function in drivers/message/fusion/mptctl.c allows local users to hold an incorrect lock during the ioctl operation
A vulnerability was found in __mptctl_ioctl in drivers/message/fusion/mptctl.c in Fusion MPT base driver 'mptctl' in SCSI device module. In this problem holding an incorrect lock can lead to a race problem, where an attacker with a local access and a special user (or root) privilege can cause denial of service (DoS) problem.
The __mptctl_ioctl function allows local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a "double fetch" vulnerability.
