Concurrent execution using shared resource with improper synchronization ('race condition') in Windows USB Video Driver allows an authorized attacker to elevate privileges locally.
AnalysisAI
Privilege escalation in the Windows USB Video Driver allows a locally authenticated attacker to gain SYSTEM-level access by exploiting a race condition in the driver's concurrent execution path. Affecting Windows releases from Server 2012 through Windows 11 26H1 and Windows Server 2025, the flaw (CWE-362) requires low-privilege code execution and tolerates no user interaction, but the high attack complexity reflects the timing window inherent to exploiting a race. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authorized (low-privileged) local user account on the target Windows system; PR:L confirms this is not a guest or anonymous attack. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H assigns a base score of 7.0, which accurately reflects the threat model: local access and low privilege are needed, but the high attack complexity (AC:H) acknowledges the timing-dependent nature of race condition exploitation. … 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 patches via Windows Update or WSUS; each affected branch has a specific target build listed in the EUVD affected-versions data (e.g., Windows 10 22H2 → 10.0.19045.7725, Windows Server 2025 → 10.0.26100.33438). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all affected Windows systems (Server 2012/2016/2019/2022/2025, Windows 8.1/10/11 including 26H1) and identify those with multi-user or non-admin user access. …
