Remote code execution via freed-memory reuse
Published Jul 11, 2023 · Updated Feb 28, 2025
Use-after-free in the Microsoft ODBC Driver on affected Windows releases allows remote attackers to execute code via crafted input. The driver references memory after freeing it while processing attacker-controlled data; Microsoft has not disclosed the responsible function or input format. Exploitation requires user interaction, and successful execution can compromise confidentiality, integrity, and availability 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.
