Code execution via undisclosed use-after-free
Published Nov 12, 2024 · Updated Jul 8, 2025
Use-after-free in affected Microsoft SQL Server 2016 SP3 through 2022 builds allows local users to execute arbitrary code. Microsoft identifies stale-memory use but has not published the affected component, freed object's reuse path, or triggering input operation. Exploitation requires local access and user interaction; success grants code execution in the affected process context.

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.
