Samsung mobile devices with N(7.x) software experience a system_server crash due to missing Intent exception handling, leading to a denial of service.
Vulnerability
An issue exists on Samsung mobile devices running N(7.x) software. The system_server process can encounter a NullPointerException because of missing Intent exception handling, causing a crash of the system process. The affected firmware versions include SVE-2017-9122, SVE-2017-9123, SVE-2017-9124, and SVE-2017-9126 (July 2017) [1].
Exploitation
An attacker does not require elevated privileges or user interaction. By sending a malformed Intent to the system_server, the lack of exception handling leads to a NullPointerException. The precise sequence of steps is not detailed in the provided references, but the vulnerability is reachable through normal Intent handling mechanisms.
Impact
Successful exploitation results in a denial of service (DoS) through a crash of the system_server process. This causes the device to become unresponsive or reboot, temporarily disrupting device operation.
Mitigation
Samsung released security patches addressing these vulnerabilities in July 2017. Users should update their devices to the latest firmware available via Samsung's security update process [1].
