DescriptionCVE.org
Out-of-bounds read in Windows DWM Core Library allows an authorized attacker to disclose information locally.
AnalysisAI
Out-of-bounds read in the Windows Desktop Window Manager (DWM) Core Library exposes sensitive memory contents to locally authenticated, low-privileged attackers on Windows 11 and Windows Server 2025. The flaw (CWE-125) allows a standard user to read beyond an allocated buffer boundary within the DWM process, resulting in high-confidence information disclosure with no integrity or availability impact. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an active local session on the affected system with at minimum a standard (low-privileged) user account - confirmed by CVSS PR:L. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 5.5 (Medium) reflects a local-only, low-privilege, no-interaction attack with high confidentiality impact but zero integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A standard domain user on a shared Windows Server 2025 Remote Desktop Services host logs in and executes a crafted application that makes malformed calls to the DWM Core Library, triggering the out-of-bounds read. The read leaks adjacent memory contents - potentially including pointers, session tokens, or credentials belonging to co-located processes - which the attacker harvests to escalate privileges or pivot laterally. … |
| Remediation | Apply the Microsoft security update that addresses this vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report. |
