Out-of-bounds read in Windows USB Hub Driver allows an unauthorized attacker to elevate privileges with a physical attack.
AnalysisAI
Privilege escalation via physical USB attack affects the Windows USB Hub Driver across a wide range of Windows 10, Windows 11, and Windows Server releases. An out-of-bounds read (CWE-125) in the kernel-mode USB Hub Driver can be triggered by an attacker who plugs a crafted USB device into an exposed port, ultimately enabling full system compromise (C:H/I:H/A:H). …

Vulnerability AssessmentAI
| Exploitation | Physical access to an exposed USB port on the target system is the sole and mandatory prerequisite; there is no network-based exploitation path. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.8 accurately reflects the physical-access requirement (AV:P), which is the dominant risk-limiting factor: an attacker must be within arm's reach of an unlocked or powered USB port. … 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-released patches for each affected Windows version via Windows Update or WSUS; exact patched build thresholds are listed in the affected products section above (e.g., Windows 11 24H2 requires build 10.0.26100.9445 or later, Windows Server 2025 requires 10.0.26100.33438 or later). … Detailed patch versions, workarounds, and compensating controls in full report. |
