In bta_pan_data_buf_ind_cback of bta_pan_act.cc there is a use after free that can result in an out of bounds read of memory allocated via malloc. This could lead to information disclosure with no additional execution privileges needed. User interaction is needed for exploitation. Product: Android. Versions: 5.1.1, 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2, 8.0, 8.1. Android ID: A-67110692.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
