In driver_override_store and driver_override_show of bus.c, there is a possible double free due to improper locking. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-69129004 References: Upstream kernel.
The product calls free() twice on the same memory address.
