Integer overflow or wraparound in Windows USB Video Driver allows an authorized attacker to elevate privileges locally.
AnalysisAI
Privilege escalation in the Windows USB Video Driver affects Windows 10, Windows 11, and Windows Server 2012 through 2025, allowing a low-privileged local attacker to elevate to SYSTEM-level access. The root cause is an integer overflow or wraparound (CWE-190) in the kernel-mode USB video driver, which under exploitation yields full confidentiality, integrity, and availability compromise of the affected host. …
