Severity by source
AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
Network-reachable unauthenticated trigger with no user interaction; kernel-mode null pointer dereference causes system-wide BSOD, justifying S:C; impact is pure availability loss with no confidentiality or integrity consequence.

Null pointer dereference in Windows Graphics Kernel allows an unauthorized attacker to deny service over a network.
AnalysisAI
Remote denial-of-service in the Windows Graphics Kernel allows unauthenticated network attackers to crash affected systems by triggering a null pointer dereference in kernel mode, impacting availability across Windows 10, Windows 11, and Windows Server 2022/2025. The CVSS Scope:Changed flag indicates the resulting crash propagates beyond the Graphics Kernel subsystem itself, consistent with a full system halt (BSOD). …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The CVSS vector (AV:N/AC:L/PR:N/UI:N) indicates no special attacker-side prerequisites: no authentication, no user interaction, and no complex attack conditions are required from the attacker's perspective. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 8.6 is driven by the network-accessible, unauthenticated, zero-interaction vector combined with Scope:Changed and high availability impact - a combination that reflects genuine concern for any organization running unpatched Windows. … 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 vendor-released patch via Windows Update or the Microsoft Update Catalog, which addresses all confirmed affected versions. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
