Blutooth BR/EDR specification does not specify sufficient encryption key length and allows an attacker to influence key length negotiation

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 Honor V10 smartphones versions earlier than Berkeley-AL20 9.0.0.125(C00E125R2P14T8) have an authorization bypass vulnerability. Due to improper authorization implementation logic, attackers can bypass certain authorization scopes of smart phones by performing specific operations. This vulnerability can be exploited to perform operations beyond the scope of authorization.

There is a race condition vulnerability on Huawei Honor V10 smartphones versions earlier than Berkeley-AL20 9.0.0.156(C00E156R2P14T8), Honor 10 smartphones versions earlier than Columbia-AL10B 9.0.0.156(C00E156R1P20T8) and Honor Play smartphones versions earlier than Cornell-AL00A 9.0.0.156(C00E156R1P13T8). An attacker tricks the user into installing a malicious application, which makes multiple processes to operate the same variate at the same time. Successful exploit could cause execution of malicious code.

Huawei smart phones have a Factory Reset Protection (FRP) bypass security vulnerability. When re-configuring the mobile phone using the factory reset protection (FRP) function, an attacker login the Talkback mode and can perform some operations to install a third-Party application.
