Remedy

As the UDF module (udf.ho) will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions: # echo "install udf /bin/true" >> /etc/modprobe.d/disable-udf.conf If the system requires this module t\work correctly, this mitigation may not be suitable. If you need further assistance, see the KCS article https://access.redhat.com/solutions/41278 or contact Red Hat Global Support Services.
