There are three out of bounds vulnerabilities in several smartphones. Certain driver program does not sufficiently validate certain parameters received, that would lead to several bytes out of bound read. Successful exploit may cause information disclosure or service abnormal. (Vulnerability ID: HWPSIRT-2019-02255, HWPSIRT-2019-03101 and HWPSIRT-2019-03103)
The three vulnerabilities have been assigned three Common Vulnerabilities and Exposures (CVE) IDs: CVE-2020-1804, CVE-2020-1805 and CVE-2020-1806.
Huawei has released software updates to fix these vulnerabilities. This advisory is available at the following link:
