Untrusted pointer dereference in Windows Secure Kernel Mode allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in Windows Secure Kernel Mode exploits an untrusted pointer dereference (CWE-822) to allow a low-privileged local attacker to elevate to full kernel-level control across a broad range of Windows 10, 11, and Server releases. The Secure Kernel Mode (SKM) context - part of Windows Virtualization-Based Security (VBS) operating at Virtual Trust Level 1 (VTL1) - means successful exploitation bypasses standard OS-kernel isolation, making this structurally more severe than a conventional LPE. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an attacker who already has local code execution with at minimum low operating-system privileges (PR:L, AV:L) - remote unauthenticated exploitation is not possible given the local attack vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 7.0 (AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects the realistic barrier to exploitation: the attacker must already have local code execution with at least low-privilege (PR:L) and must navigate high attack complexity (AC:H), consistent with the pointer-manipulation primitives typically required for SKM-class exploits. … 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 | Vendor-released patches are available for all affected Windows versions via the standard Windows Update mechanism. … Detailed patch versions, workarounds, and compensating controls in full report. |
