First published: Thu Sep 02 2021(Updated: )

Remedy

As the SCTP module will be auto-loaded when required, its use can be disabled by preventing the module from loading with the following instructions: if # echo "install sctp /bin/true" >> /etc/modprobe.d/disable-sctp.conf The system will need to be restarted if the SCTP modules are loaded. In most circumstances, the SCTP kernel modules 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.
