Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify SQL Server installation and versionOpen SQL Server Configuration Manager or run 'SELECT @@VERSION' in SQLCMD to retrieve the installed SQL Server version and build number.Affected if The installed version falls within any of the affected version ranges: 13.0.6300.2 to 13.0.6441.1, 13.0.7000.253 to 13.0.7037.1 (SQL 2016); 14.0.1000.169 to 14.0.2056.2, 14.0.3006.16 to 14.0.3471.2 (SQL 2017); 15.0.2000.5 to 15.0.2116.2, 15.0.4003.23 to 15.0.4382.1 (SQL 2019); 16.0.1000.6 to 16.0.11
-
Confirm SQL Server Native Client OLE DB Provider is installedCheck the Windows Registry under HKLM\SOFTWARE\Microsoft\Microsoft SQL Server\SQL_<InstanceName>\Providers or look for 'SQLOLEDB' in the list of OLE DB providers via SQL Server Management Studio under Server Objects > Linked Servers > Providers.Affected if The SQLOLEDB provider appears in the list of installed OLE DB providers for the SQL Server instance.
-
Verify OLE DB Provider is actively in useQuery sys.servers with provider='SQLOLEDB' or inspect application connection strings for 'Provider=SQLOLEDB' or 'Provider=SQLNCLI11' to determine if any applications or linked servers use the Native Client OLE DB interfaces.Affected if Any linked server, distributed query, or application connection string references the SQL Server Native Client OLE DB provider.
You are affected if your SQL Server version is within the affected ranges AND the SQL Server Native Client OLE DB Provider (SQLOLEDB) is installed and in use.

Apply the appropriate Microsoft security update for SQL Server Native Client OLE DB Provider. Prioritize patching for any internet-facing SQL Server systems running the native client OLE DB interfaces.
SQL Server 2016: CU14 (13.0.6441.1) or CU22 (13.0.7037.1); SQL Server 2017: CU31 (14.0.2056.2) or CU26 (14.0.3471.2); SQL Server 2019: CU23 (15.0.2116.2) or CU30 (15.0.4382.1); SQL Server 2022: CU12 (16.0.1121.4) or CU6 (16.0.4131.2)
- 1. Identify the exact SQL Server version currently installed by running: SELECT @@VERSION
- 2. Based on your SQL Server version (2016, 2017, 2019, or 2022), apply the corresponding Cumulative Update (CU) that contains the fix:
- - SQL Server 2016: Apply CU14 (13.0.6441.1) or later for versions 13.0.6300.2-13.0.6441.0; Apply CU22 (13.0.7037.1) or later for versions 13.0.7000.253-13.0.7037.0
- - SQL Server 2017: Apply CU31 (14.0.2056.2) or later for versions 14.0.1000.169-14.0.2056.1; Apply CU26 (14.0.3471.2) or later for versions 14.0.3006.16-14.0.3471.1
- - SQL Server 2019: Apply CU23 (15.0.2116.2) or later for versions 15.0.2000.5-15.0.2116.1; Apply CU30 (15.0.4382.1) or later for versions 15.0.4003.23-15.0.4382.0
- - SQL Server 2022: Apply CU12 (16.0.1121.4) or later for versions 16.0.1000.6-16.0.1121.3; Apply CU6 (16.0.4131.2) or later for versions 16.0.4003.1-16.0.4131.1
- 3. Download and install the appropriate Cumulative Update from the Microsoft Update Catalog or through Windows Update
- 4. After installation, verify the version has been updated by running: SELECT @@VERSION
