CVE-2020-12652

A vulnerability was found in __mptctl_ioctl in drivers/message/fusion/mptctl.c in Fusion MPT base driver ‘mptctl’ in the SCSI device module, where an incorrect lock leads to a race problem. This flaw allows an attacker with local access and special user (or root) privileges to cause a denial of service.

Mitigation

Mitigation for this issue is to skip loading the affected module Fusion MPT base driver 'mptctl' onto the system until we have a fix available. This can be done by a blacklist mechanism and will ensure the driver is not loaded at the boot time.

How do I blacklist a kernel module to prevent it from loading automatically?
