AnalysisAIv1 – Sep 09, 2026

Heap-based buffer overflow in the Windows USB Audio Class kernel driver (usbaudio.sys) enables a locally authenticated, low-privileged attacker to escalate privileges to SYSTEM on affected Windows hosts. The vulnerability spans virtually every supported Windows release from Server 2012 through Windows 11 26H1 and requires no user interaction beyond the attacker's own session. No public exploit code or CISA KEV listing has been identified at time of analysis; vendor patch is available via Microsoft Update.

DescriptionCVE.org

Heap-based buffer overflow in Windows USB Audio Class driver (usbaudio.sys) allows an authorized attacker to elevate privileges locally.

Executive ViewAI

Why It Matters

A privilege escalation vulnerability in the Windows USB Audio Class kernel driver affects all supported Windows versions (Server 2012 through Windows 11) and allows authenticated local users to gain full SYSTEM-level administrative privileges. Organizations face heightened insider-threat risk where non-administrative users have physical or remote access to systems, as attackers can exploit this to bypass security controls and compromise system integrity.

Recommended Action

Within 24 hours, identify all Windows endpoints and servers affected (Server 2012 through Windows 11 26H1) and segregate systems with guest or contractor access as priority targets. Within 7 days, deploy the Microsoft patch for usbaudio.sys across all affected systems through Windows Update or manual security updates. Within 30 days, verify deployment completion, audit local user access policies to restrict unnecessary local logins, and implement application whitelisting on high-value systems to prevent post-exploitation persistence.

Business Impact: High
Compensating Controls

Apply vendor patch.

Attack Technique

Buffer Overflow HIGH

A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.

Heap Overflow HIGH

A heap overflow occurs when a program writes data beyond the bounds of a buffer allocated in the heap memory region.
