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. Affected products can be found in https://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200115-01-frp-en.

There are two denial of service vulnerabilities on some Huawei smartphones. An attacker may send specially crafted TD-SCDMA messages from a rogue base station to the affected devices. Due to insufficient input validation of two values when parsing the messages, successful exploit may cause device abnormal. This is 1 out of 2 vulnerabilities. Different than CVE-2020-5303. Affected products are: ALP-AL00B: earlier than 9.1.0.333(C00E333R2P1T8) ALP-L09: earlier than 9.1.0.300(C432E4R1P9T8) ALP-L29: earlier than 9.1.0.315(C636E5R1P13T8) BLA-L29C: earlier than 9.1.0.321(C636E4R1P14T8), earlier than 9.1.0.330(C432E6R1P12T8), earlier than 9.1.0.302(C635E4R1P13T8) Berkeley-AL20: earlier than 9.1.0.333(C00E333R2P1T8) Berkeley-L09: earlier than 9.1.0.350(C10E3R1P14T8), earlier than 9.1.0.351(C432E5R1P13T8), earlier than 9.1.0.350(C636E4R1P13T8) Charlotte-L09C: earlier than 9.1.0.311(C185E4R1P11T8), earlier than 9.1.0.345(C432E8R1P11T8) Charlotte-L29C: earlier than 9.1.0.325(C185E4R1P11T8), earl…

Huawei smart phones Emily-L29C with Versions earlier than 9.1.0.311(C10E2R1P13T8), Versions earlier than 9.1.0.311(C461E2R1P11T8), Versions earlier than 9.1.0.316(C635E2R1P11T8), Versions earlier than 9.1.0.311(C185E2R1P12T8), Versions earlier than 9.1.0.311(C605E2R1P12T8), Versions earlier than 9.1.0.311(C636E7R1P13T8) have an information leakage vulnerability. An attacker tricks the user into installing a malicious application, which can copy specific files to the sdcard, resulting in information leakage.

Bastet module of some Huawei smartphones with Versions earlier than Emily-AL00A 9.0.0.182(C00E82R1P21), Versions earlier than Emily-TL00B 9.0.0.182(C01E82R1P21), Versions earlier than Emily-L09C 9.0.0.203(C432E7R1P11), Versions earlier than Emily-L29C 9.0.0.203(C432E7R1P11), Versions earlier than Emily-L29C 9.0.0.202(C185E2R1P12) have a double free vulnerability. An attacker tricks the user into installing a malicious application, which frees on the same memory address twice. Successful exploit could result in 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 Emily-L29C with versions of 8.1.0.132a(C432), 8.1.0.135(C782), 8.1.0.154(C10), 8.1.0.154(C461), 8.1.0.154(C635), 8.1.0.156(C185), 8.1.0.156(C605), 8.1.0.159(C636) have a double free vulnerability. An attacker can trick a user to click a URL to exploit this vulnerability. Successful exploitation may cause the affected phone abnormal.

Emily-L29C Huawei phones versions earlier than 9.0.0.159 (C185E2R1P12T8) have a Factory Reset Protection (FRP) bypass security vulnerability. Before the FRP account is verified and activated during the reset process, the attacker can perform some special operations to bypass the FRP function and obtain the right to use the mobile phone.
