In reassemble_and_dispatch of packet_fragmenter.cc, there is possible out of bounds write due to an incorrect bounds calculation. This could lead to remote code execution over Bluetooth with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-8.0 Android-8.1 Android-9 Android-10Android ID: A-143894715

In the ioctl handlers of the Mediatek Command Queue driver, there is a possible out of bounds write due to insufficient input sanitization and missing SELinux restrictions. This could lead to local escalation of privilege with no additional execution privileges needed.

There is an improper authentication vulnerability in Huawei smartphones (Y9, Honor 8X, Honor 9 Lite, Honor 9i, Y6 Pro). The applock does not perform a sufficient authentication in a rare condition. Successful exploit could allow the attacker to use the application locked by applock in an instant.

The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.

Huawei Enjoy 5s and Y6 Pro smartphones with software the versions before TAG-AL00C92B170; the versions before TIT-L01C576B121 have an information leak vulnerability due to the lack of parameter validation. An attacker tricks a user into installing a malicious application on the smart phone and the application can read some sensitive information in kernel memory which may cause sensitive information leak.

TIT-AL00 smartphones with software versions earlier before TIT-AL00C583B214 have a exposed system interface vulnerability. The software provides a system interface for interaction with external applications, but calling the interface is not properly restricted. An attacker could trick the user into installing a malicious application to call the interface and modify the system properties.
