Microsoft Windows USB Video Driver: Double free allows local privilege escalation
Summary
A double free vulnerability (CWE-415) in the Windows USB Video Driver allows an authorized local attacker to elevate privileges. The attacker needs a valid low-privileged user account on the host and a complex attack path (AC:H), and the flaw cannot be exploited remotely. CVSS v3.1 is 7.0 (High), and the CNA reports total technical impact.
