description

Microsoft SQL Server 2017, 2019, 2022, and 2025 releases in the affected servicing branches contain a heap-based buffer overflow. An unauthenticated attacker able to reach the SQL Server service over a network may execute code on the affected server.

mitigation

Install the applicable SQL Server security update: 14.0.2150.2 or 14.0.3570.2 for 2017, 15.0.2210.4 or 15.0.4510.2 for 2019, 16.0.1220.3 or 16.0.4315.2 for 2022, or 17.0.5045.3 or 17.0.1155.3 for 2025. Until patched, restrict network access to SQL Server to trusted clients.

fixed in 14.0.2150.2, 14.0.3570.2, 15.0.2210.4, 15.0.4510.2, 16.0.1220.3, 16.0.4315.2, 17.0.5045.3, 17.0.1155.3
