What is CVE-2018-9417?

The use-after-free vulnerability in Android HID devices arises from improper locking mechanisms within the f_hid.c source code, specifically in the f_hidg_read and hidg_disable functions. This flaw permits local privilege escalation, enabling unauthorized access to sensitive system functions without requiring additional execution privileges. Exploitation can occur without direct user interaction, making this a critical security concern for devices leveraging the Android OS.
