Out-of-bounds read in SQL Server allows an authorized attacker to execute code over a network.
AnalysisAI
Out-of-bounds read in Microsoft SQL Server 2019, 2022, and 2025 enables an authenticated low-privilege attacker to execute arbitrary code over the network with scope-changed impact. The CWE-125 memory safety flaw in the database engine is reachable via standard SQL Server network access, and the scope-changed CVSS vector (S:C) indicates successful exploitation can escape the SQL Server process boundary to affect the underlying host. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid SQL Server login with at least low-privilege access (PR:L)-any authenticated principal, including application service accounts with minimal grants, can serve as the attack vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.5 score reflects genuine severity: network reachability, no user interaction, and a scope-changed full-triad impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply Microsoft's vendor-released patches for the relevant SQL Server servicing track: SQL Server 2019 GDR to 15.0.2190.7, SQL Server 2019 CU 32 to 15.0.4490.9, SQL Server 2022 GDR to 16.0.1200.5, SQL Server 2022 CU 26 to 16.0.4275.2, SQL Server 2025 GDR to 17.0.1135.8, and SQL Server 2025 CU8 to 17.0.4085.5. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct a complete inventory of SQL Server 2019, 2022, and 2025 deployments and audit database user access controls to eliminate unnecessary low-privilege accounts with network connectivity. …
