CVE-2020-9383

An out-of-bounds (OOB) memory access flaw was found in the floppy driver module in the Linux kernel. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability.

Mitigation

Mitigation for this issue is to skip loading the affected floppy driver module onto the system till we have a fix available, this can be done by a blacklist mechanism, this will ensure the driver is not loaded at the boot time.

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