Improper Restriction of Operations within the Bounds of a Memory Buffer
The inputhub driver of HUAWEI P9 Lite mobile phones with Versions earlier than VNS-L21C02B341, Versions earlier than VNS-L21C22B380, Versions earlier than VNS-L31C02B341, Versions earlier than VNS-L31C440B390, Versions earlier than VNS-L31C636B396 has a buffer overflow vulnerability due to the lack of parameter validation. An attacker tricks a user into installing a malicious APP and the APP may sends specific data to the inputhub driver to exploit this vulnerability, successful exploit could cause the system reboot.
CWE-119 - Buffer Overflow
Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
