Authenticated memory disclosure via out-of-bounds read
Published Sep 8, 2026 · Updated Sep 10, 2026
Out-of-bounds read in Microsoft SQL Server 2019, 2022, and 2025 allows remote authenticated users to disclose server memory. Microsoft identifies the Database Engine as affected but has not published the input, function, or code path that performs the out-of-bounds read. A valid database login and network access are required, and the reported impact is confined to reading memory rather than altering data or interrupting service.
