The MIB's DESCRIPTION for cucsLicenseInstanceFsmCurrentFsm is only the auto-generated stub 'Cisco UCS license:InstanceFsm:currentFsm managed object property', but the 'currentFsm' property name together with its CucsLicenseInstanceFsmCurrentFsm type tell us this column, on the FSM that tracks a license instance's activation/deactivation transitions, holds the currentFsm as UCS Manager's data model defines it, exposed here as a read-only SNMP value (read-only). The currentFsm names which specific state machine is currently driving the FSM that tracks a license instance's activation/deactivation transitions — UCS Manager runs different named FSMs for different license operations (e.g. installing a file versus activating an instance), and this field tells you which one is active right now. During a license-file install this might read something like 'LicenseFileInstall', switching to a different named FSM once installation finishes and activation begins.
