Local privilege escalation via administrator process attachment
Published Jan 25, 2023 · Updated Mar 28, 2025
Improper authorization in Dell's Realtek audio driver allows local users to elevate privileges by attaching to an administrator process. Dell has not disclosed the affected routine or precise missing access-control check; the published mechanism is attachment to the launched process. Exploitation requires existing local access, an administrator to launch the application, and attachment to that process, after which system privileges are obtained.
