SQL Server: linked server MSDASQL queries with provider string fail with error 7416

Linked server queries that use the MSDASQL provider (OLE DB Provider for ODBC Drivers) and specify a provider string ([user]) fail with error 7416 for users who are not sysadmin. A stricter connection validation check in the Database Engine causes this. Microsoft confirms the issue and states it is addressed starting with the October 2026 GDR update.
