Remediation
Red Hat mitigation
As the ath10k module will be auto-loaded when required, its use can be disabled by preventing the module from loading using the following instructions. On the command line, as root, execute the following command: # echo "install ath10k_usb /bin/true" >> /etc/modprobe.d/disable-ath10k_usb.conf The system will need to be restarted if the ath10k_usb module are loaded. In most circumstances, the kernel modules will be unable to be unloaded while the ath10k WiFi network interface is 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.
