CVE-2019-5303: Huawei Alp-AL00B Firmware

Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

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 2 out of 2 vulnerabilities. Different than CVE-2020-5302.
