✅ 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: Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible. 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: No current mitigation is available for this vulnerability. Please make sure to have kernel up-to-date as soon as the patches are available to make sure the flaw mitigated. Workaround: In order to trigger the issue, it requires the ability to create user/net namespaces. On non-containerized deployments of Red Hat Enterprise Linux 8, you can disable user namespaces by setting user.max_user_namespaces to 0: # echo "user.max_user_namespaces=0" > /etc/sysctl.d/userns.conf # sysctl -p /etc/sysctl.d/userns.conf On containerized deployments, such as Red Hat OpenShift Container Platform, do not use this mitigation as the functionality is needed to be enabled. Workaround: The TIPC module is not automatically loaded in default configurations. When required, administrative privileges are required to explicitly load this module. To determine if the TIPC module is loaded, use the following command: # grep tipc /proc/modules Look for output similar to the following: tipc 479232 0 - Live 0xffffffffc1ba5000 ip6_udp_tunnel 16384 1 tipc, Live 0xffffffffc1b9b000 udp_tunnel 32768 1 tipc, Live 0xffffffffc1b8b000 Loading the module can be prevented with the following instructions: # echo "install tipc /bin/true" >> /etc/modprobe.d/disable-tipc.conf The system will need to be restarted if the module is loaded. In most circumstances, the TIPC kernel module will be unable to be unloaded while any network interfaces are active and the protocol is in use. If the system requires this module to work correctly, this mitigation may not be suitable.
