Use after free in Windows Device Association Service allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in the Windows Device Association Service allows a low-privileged attacker to gain SYSTEM-level access on unpatched systems via a use-after-free memory corruption bug (CWE-416). The vulnerability spans the entire current Windows ecosystem - from Windows 10 1607 and Server 2012 R2 through Windows 11 25H2 and Server 2025 - making the attack surface extremely broad. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must possess a valid low-privilege account with the ability to execute code locally on the target system (PR:L, AV:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.0 score with vector AV:L/AC:H/PR:L/UI:N reflects a meaningful but operationally constrained threat: an attacker must already hold a local account with limited privileges, and exploitation requires navigating a high-complexity condition (likely a race or precise heap-grooming sequence). … 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 security updates released for CVE-2026-69488 via Windows Update or WSUS; exact target build numbers for each branch are listed in the EUVD affected-versions data (e.g., Windows Server 2025 to 10.0.26100.33438, Windows 10 22H2 to 10.0.19045.7725). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Windows systems across your organization (Windows 10 1607-22H2, Windows 11 21H2-25H2, Windows Server 2012 R2, 2016, 2019, 2022, 2025) and classify by criticality; contact your patch management team to verify current coverage via WSUS, Intune, or configuration management tools. …
