Code execution via use-after-free
Published Nov 12, 2024 · Updated Jul 8, 2025
Use-after-free in Microsoft SQL Server 2016 SP3, 2017, and 2019 allows remote attackers to execute code through Native Client. Microsoft identifies the memory-lifetime weakness but has not published the affected function, freed object, or triggering input. Exploitation is network-based and unauthenticated but requires user interaction; successful exploitation runs code in the affected client 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.
- Affected versionversion=13.0.0 <13.0.7050.2
