Mitigation checklist
- If iSCSI offload engine functionality is not required, the `iscsiuio` service can be disabled to prevent exploitation. This action will stop the service immediately and prevent it from starting on subsequent reboots. To disable the `iscsiuio` service: ```bash sudo systemctl disable --now iscsiuio.service sudo systemctl mask iscsiuio.service ``` *Disabling this service will impact any systems relying on iSCSI offload engines. A system restart or service reload may be required for the changes to take full effect.
