CVE-2022-1652

A use-after-free flaw was found in the Linux kernel’s floppy driver implementation. This flaw allows a local attacker to possibly corrupt memory.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

The floppy module will be auto-loaded when the hardware is present. Its loading can be prevented with the following instructions:

echo "install floppy /bin/true" >> /etc/modprobe.d/disable-floppy.conf

The system will need to be restarted if the floppy modules is loaded. In most circumstances, the floppy kernel modules will be unable to be unloaded while is in use.

If the system requires this module to work correctly, this mitigation may not be suitable.
