The patch adds access control to prevent unauthorized access. There are several vulnerabilities in the Bluetooth core protocol as listed below. When an attacker connects to a victim device using the address of the device and the victim initiates a Pairing, the attacker can reflect the encrypted nonce even without knowledge of the key. The authentication property of the Bluetooth LE Legacy Pairing procedures is vulnerable to a reflection attack.
A remote attacker without knowledge of the token key can complete the authentication protocol. The patch fixes exception handling for the Bluetooth core protocol.

The most severe of these issues is a high security vulnerability in the Media Framework component that could enable a local malicious application to bypass operating system protections that isolate application data from other applications.
The severity assessment is based on the effect that exploiting the vulnerability would possibly have on an affected device, assuming the platform and service mitigations are turned off for development purposes or if successfully bypassed.
Refer to the Android and Google Play Protect mitigations section for details on the Android security platform protections and Google Play Protect, which improve the security of the Android platform. This is a summary of the mitigations provided by the Android security platform and service protections such as Google Play Protect.
These capabilities reduce the likelihood that security vulnerabilities could be successfully exploited on Android.
