Buffer over-read in SQL Server allows an authorized attacker to disclose information over a network.
AnalysisAI
SQL Server information disclosure via buffer over-read (CWE-126) allows an authenticated low-privilege network attacker to read memory contents beyond an intended buffer boundary, potentially exposing sensitive in-process data. The flaw spans SQL Server 2017, 2019, 2022, and 2025 across both GDR and Cumulative Update servicing branches, making the affected population broad. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid SQL Server login with at least low-privilege database access (consistent with PR:L in the CVSS vector); unauthenticated network access is insufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 (Medium) score is well-calibrated for this class of vulnerability: network-reachable, low complexity, low-privilege, and confidentiality-only 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 the relevant Microsoft-released patch for the installed SQL Server branch. … Detailed patch versions, workarounds, and compensating controls in full report. |
