Technical Description
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), earli
Remediation
Check the references section for vendor advisories and patches from huawei. Update alp-al00b_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
