Information disclosure via out-of-bounds read
Published Sep 8, 2026 · Updated Sep 10, 2026
Out-of-bounds read in Microsoft SQL Server 2017 through 2025 allows remote authenticated users to disclose information over a network. Microsoft has not published the affected code locus or the input that causes a read beyond the intended buffer boundary. Low-privileged database access is sufficient, and the documented consequence is limited to unauthorized information disclosure.

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=16.0.0.0 <16.0.4275.2
- Affected versionversion=16.0.0 <16.0.1200.5
