Use after free in Windows License Manager allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in Windows License Manager exposes authenticated local users to full system compromise via a use-after-free condition (CWE-416). An attacker with a low-privileged local session who can win a memory-management race condition can corrupt heap state and redirect execution to gain SYSTEM-level privileges across a wide range of Windows 10, 11, and Server editions. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an existing authenticated local session with at minimum low-privilege access on the target Windows system (PR:L, AV:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 7.0 reflects a meaningful but not automatic exploitation barrier: AC:H signals that the use-after-free is race-condition-dependent, requiring non-trivial timing or heap-grooming to exploit reliably. … 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 | Microsoft has released cumulative updates addressing this vulnerability across all affected Windows editions. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory Windows 10 (1809+), Windows 11 (all versions), and Windows Server (2019-2025) deployments in your environment, prioritizing multi-user systems, RDP gateways, and shared workstations. …
