Certain detection module of P30, P30 Pro, Honor V20 smartphone whith Versions earlier than ELLE-AL00B 9.1.0.193(C00E190R1P21), Versions earlier than VOGUE-AL00A 9.1.0.193(C00E190R1P12), Versions earlier than Princeton-AL10B 9.1.0.233(C00E233R4P3) have a race condition vulnerability. The system does not lock certain function properly, when the function is called by multiple processes could cause out of bound write. An attacker tricks the user into installing a malicious application, successful exploit could cause malicious code execution.

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 smart phones Honor V20 with the versions before 9.0.1.161(C00E161R2P2) have an information leak vulnerability. An attacker may trick a user into installing a malicious application. Due to coding error during layer information processing, attackers can exploit this vulnerability to obtain some layer information.

There is an information disclosure vulnerability on Secure Input of certain Huawei smartphones in Versions earlier than Tony-AL00B 9.1.0.216(C00E214R2P1). The Secure Input does not properly limit certain system privilege. An attacker tricks the user to install a malicious application and successful exploit could result in information disclosure.

There is a Factory Reset Protection (FRP) bypass vulnerability on several smartphones. The system does not sufficiently verify the permission, an attacker could do a certain operation on certain step of setup wizard. Successful exploit could allow the attacker bypass the FRP protection. Affected products: Mate 20 X, versions earlier than Ever-AL00B 9.0.0.200(C00E200R2P1); Mate 20, versions earlier than Hima-AL00B/Hima-TL00B 9.0.0.200(C00E200R2P1); Honor Magic 2, versions earlier than Tony-AL00B/Tony-TL00B 9.0.0.182(C00E180R2P2).

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 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 an information leak vulnerability in some Huawei smartphones. An attacker may do some specific configuration in the smartphone and trick a user into inputting some sensitive information. Due to improper design, successful exploit may cause some information leak.

When re-configuring the mobile phone using the factory reset protection (FRP) function, an attacker can disable the boot wizard by ena…

The Themes App Honor 8 Lite Huawei mobile phones with software of versions before Prague-L31C576B172, versions before Prague-L31C530B160, versions before Prague-L31C432B180 has a man-in-the-middle (MITM) vulnerability due to the use of the insecure HTTP protocol for theme download. An attacker may exploit this vulnerability to tamper with downloaded themes.
