Authenticated memory disclosure via out-of-bounds read
Published Sep 8, 2026 · Updated Sep 10, 2026
Out-of-bounds read in Microsoft SQL Server 2025 allows remote authenticated users to disclose server memory over a network. Microsoft identifies an out-of-bounds read in SQL Server but has not published the affected function, input field, or failing bounds operation. Low-privileged SQL Server access and network reachability are required; the published impact is memory disclosure without integrity or availability loss.
