Since KB5003173 was release in May there has been an issue with current CU not including the required SSU to be installed.
Is this going to be fixed in upcoming updates? This is an issue because current updates supersedes this update but they cannot be installed as the SSU in the May update is a pre-requisite.
This is creating issues for organizations that use WSUS as current updates are downloaded to client machines from the WSUS server and fail to install because the SSU version is incorrect.
If an update is cumulative it need to include the SSU update required to install itself.
