Use after free in Windows Device Association Service allows an authorized attacker to elevate privileges locally.
AnalysisAI
Use-after-free in the Windows Device Association Service enables a low-privileged local attacker to escalate to full system control across a broad range of Windows 10, Windows 11, and Windows Server releases. The flaw (CWE-416) resides in the service responsible for managing device pairing and trust relationships, and exploitation yields high confidentiality, integrity, and availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must have local interactive or remote desktop access to the target system with at least a low-privileged (non-guest) account - the CVSS PR:L metric confirms this prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.0 score accurately reflects the constrained exploitation environment: local access and high attack complexity both narrow the realistic attacker population compared to network-reachable, low-complexity vulnerabilities. … 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 update for the affected Windows version through Windows Update or WSUS immediately. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Windows 10, Windows 11, and Windows Server systems to identify affected builds and document current patch levels. …
