- Mitigation guidance
- To mitigate this issue, ensure the `mmpstrucdata` plugin is not loaded or used in rsyslog configurations where it is not essential. If the plugin is required, restrict network access to the rsyslog service to trusted sources. Additionally, review and adjust the `MaxMessageSize` configuration to prevent the processing of excessively large structured-data parameters. *Warning: Changes to rsyslog configuration may require a service restart, which will temporarily interrupt log collection.*
