Use after free in Windows Autopilot allows an authorized attacker to elevate privileges locally.
AnalysisAI
Privilege escalation in Windows Autopilot on Windows 11 (versions 24H2, 25H2, and 26H1) is caused by a use-after-free memory corruption flaw (CWE-416) that allows a locally authenticated low-privileged attacker to achieve SYSTEM-level access. The CVSS 7.0 score reflects full CIA impact offset by a strictly local attack vector and high attack complexity, consistent with a race condition or heap manipulation requirement rather than a trivial trigger. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires an attacker to possess an existing authenticated local session with at least low-privilege access (confirmed by PR:L in the CVSS vector) on a Windows 11 device running one of the affected Autopilot-integrated builds. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.0 base score (AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H) correctly captures a serious but constrained threat. … 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 Microsoft Update Catalog targeting the following fixed builds: 10.0.26200.9168 or later for Windows 11 25H2, 10.0.26100.9168 or later for Windows 11 24H2, and 10.0.28000.2704 or later for Windows 11 26H1, per the Microsoft Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-65779. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Windows 11 devices running Autopilot in versions 24H2, 25H2, or 26H1 to establish affected asset count and exposure scope. …
