Base vector

AV:N/AC:M/Au:N/C:C/I:C/A:C

Name of the Vulnerable Software and Affected Versions Huawei smart phones versions earlier than NEM-AL10C00B356 Huawei smart phones versions earlier than Berlin-L21HNC432B360

Description The issue is caused by a buffer overflow due to the lack of parameter validation in the driver. An attacker can trick a user into installing a malicious APP with root privilege, which can send a specific parameter to the driver, potentially causing a system reboot or arbitrary code execution.

Recommendations For versions earlier than NEM-AL10C00B356, avoid installing APPs from untrusted sources and restrict the use of root privileges until a patch is available. For versions earlier than Berlin-L21HNC432B360, consider disabling the installation of APPs with root privilege as a temporary workaround until a fix is provided.
