Executive brief
A security vulnerability exists in the Windows USB driver, which manages how the computer communicates with USB devices. An attacker who already has basic access to a computer could exploit this flaw to gain full administrative control over the system. This could allow them to view sensitive data, install malicious software, or disrupt business operations.
Technical details
A race condition (CWE-362) exists in the Windows USB Driver due to improper synchronization when accessing shared resources. This flaw can lead to a use-after-free (CWE-416) condition. An attacker with local access and low-level privileges can exploit this vulnerability without any user interaction. Successful exploitation allows the attacker to execute code with elevated system privileges. Microsoft has released security updates to address this issue across affected Windows and Windows Server versions.
