Out-of-bounds read in SQL Server allows an authorized attacker to disclose information over a network.
AnalysisAI
Out-of-bounds read in Microsoft SQL Server (versions 2017 through 2025) allows a low-privileged authenticated attacker to disclose sensitive information over the network by triggering a memory read beyond an allocated buffer boundary. The CVSS vector confirms network-accessible exploitation requiring only low-privilege credentials (PR:L), with no user interaction needed, resulting in high confidentiality impact. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid SQL Server login with at least low-privilege access (PR:L per CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 rating with vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N reflects a moderate-to-significant risk: the attack is low-complexity and requires only a valid SQL Server login, which is a realistic attacker posture in many environments - even a mid-sized municipal IT team in boleslawiec running SQL Server with numerous application service accounts would have non-trivial exposure. … 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 Microsoft-released patches for the appropriate SQL Server version and servicing track. … Detailed patch versions, workarounds, and compensating controls in full report. |
