CVE-2018-9139

Vulnerability

A buffer overflow vulnerability exists in the vision service on Samsung mobile devices running Android N(7.x). The issue is triggered by a large frame size, leading to memory corruption. Affected versions include all devices with N(7.x) software. The vulnerability is tracked as SVE-2017-11165 [1].

Exploitation

An attacker can exploit this vulnerability by providing a large frame size to the vision service. No authentication is required, but the attacker must be able to send crafted input to the service, likely through a malicious application or local access. The exact attack vector is not publicly detailed.

Impact

Successful exploitation allows code execution in a privileged process, granting the attacker elevated system-level permissions. This can lead to full compromise of the device's security mechanisms, including arbitrary code execution and potential data exfiltration.

Mitigation

Samsung released security updates to address this vulnerability. Users should apply the latest security patch level from Samsung, which includes the fix for this issue. The update is part of the Samsung Mobile Security maintenance release for March 2018 or later [1]. No workaround is available.
