✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. Workaround: Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. Workaround: As the FUSE module will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions: # echo "install fuse /bin/true" >> /etc/modprobe.d/disable-fuse.conf The system will need to be restarted if the FUSE modules are loaded. In most circumstances, the CIFS kernel modules will be unable to be unloaded while the FUSE filesystems are 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. Workaround: To mitigate this issue, prevent the module firedtv from being loaded. Please see https://access.redhat.com/solutions/41278 for information on how to blacklist a kernel module to prevent it from loading automatically.
