A BMC record can contain a corrupted free-text value with a line break, for example one of several identical NVIDIA H200 NVL GPUs reporting its model as 900-2101 followed by G40-000 on a new line. The Redfish CPU service then crashed with ValueError: '\n' not allowed in 'summary'.

The CPU service and most other Redfish services now replace line breaks in values reported by the BMC by spaces.
