Two Denial of Service Vulnerabilities on Some Huawei Smartphones

  • SA No:huawei-sa-20190814-01-mobile
  • Initial Release Date: 2019-08-14
  • Last Release Date: 2020-09-02

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 an infinite loop and the device to reboot. (Vulnerability ID: HWPSIRT-2019-05093 and HWPSIRT-2019-05095)

The two vulnerabilities have been assigned two Common Vulnerabilities and Exposures (CVE) IDs: CVE-2019-5302 and CVE-2019-5303.

Huawei has released software updates to fix these vulnerabilities. This advisory is available at the following link:

Successful exploit may cause an infinite loop and the device to reboot.

The vulnerability classification has been performed by using the CVSSv3 scoring system (http://www.first.org/cvss/specification-document).

HWPSIRT-2019-05093 and HWPSIRT-2019-05095:

Base Score: 5.3 (AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

Temporal Score: 4.9 (E:F/RL:O/RC:C)


HWPSIRT-2019-05093 and HWPSIRT-2019-05095:

This vulnerability can be exploited only when the following conditions are present:

1. The affected device is working in TD-SCDMA mode.

Vulnerability details:

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 an infinite loop and the device to reboot.


The product that supports automatic update will receive a system update prompt. You can install the update to fix the vulnerability.

These two vulnerabilities were discovered by Huawei internal tester.
