The Dolby DAX2 and DAX3 API services are vulnerable to a privilege escalation vulnerability that allows a normal user to get arbitrary system privileges, because these services have .NET code for DCOM. This affects Dolby Audio X2 (DAX2) 1.0, 1.0.1, 1.1, 1.1.1, 1.2, 1.3, 1.3.1, 1.3.2, 1.4, 1.4.1, 1.4.2, 1.4.3, and 1.4.4 and Dolby Audio X3 (DAX3) 1.0 and 1.1. An example affected driver is Realtek Audio Driver 6.0.1.7898 on a Lenovo P50.
