Remediation
Red Hat mitigation
As the multitouch module will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions: # echo "install hid-multitouch /bin/true" >> /etc/modprobe.d/disable-hid-multitouch.conf The system may need to be restarted if the hid-multitouch module is loaded. In most circumstances, a kernel modules will be unable to be unloaded while in use. If the system requires this module to work correctly, this mitigation may not be suitable. If you need further assistance, see KCS article https://access.redhat.com/solutions/41278 or contact Red Hat Global Support Services.
