✅ 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: To mitigate this vulnerability, prevent the `bcm` kernel module from loading by blacklisting it. Create a file named `/etc/modprobe.d/blacklist-bcm.conf` with the following content: ``` blacklist bcm ``` After creating the file, regenerate the initramfs and reboot the system for the changes to take effect. This mitigation may impact systems that rely on CAN BCM functionality. If CAN BCM is required, this mitigation is not suitable. A system reboot is required for the changes to take effect. Workaround: Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability. Workaround: To mitigate this issue, prevent module snd-usb-audio from being loaded. As the snd_usb_audio module will be auto-loaded when a usb device is hot plugged, the module can be prevented by loading with the following instructions: # echo "install snd_usb_audio /bin/true" >> /etc/modprobe.d/disable-snd-usb-audio.conf The system will need to be restarted if the modules are loaded. In most circumstances, the sound kernel modules will be unable to be unloaded while any programs are active and the device 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.
