In the doGetThumb and getThumbnail functions of MtpServer, there is a possible double free due to not NULLing out a freed pointer. This could lead to an local elevation of privilege enabling code execution as a privileged process with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: 7.0, 7.1.1, 7.1.2, 8.0, 8.1. Android ID: A-67864232.
The product calls free() twice on the same memory address.
