Service interruption via malformed TDS packet
Published Oct 10, 2023 · Updated Apr 14, 2025
Out-of-bounds read in Microsoft SQL Server and its data-access drivers allows local users to interrupt service with a malformed TDS packet. The SQL Server security infrastructure reads beyond a buffer boundary while processing malformed Tabular Data Stream packet data, producing login failure, unavailability, or undefined behavior. A low-privileged local position is required; the documented consequence is service availability loss, not data disclosure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
