CVE-2022-27569

Vulnerability

A heap-based buffer overflow vulnerability exists in the parser_infe function of the libsimba library prior to the SMR Apr-2022 Release 1. This allows a remote attacker to trigger code execution. Affected versions include all Samsung mobile devices running firmware releases before the April 2022 Security Maintenance Release [1].

Exploitation

The attacker requires network access to the target device and must send a specially crafted input that is processed by the vulnerable parser_infe function. No authentication is needed; the attack can be carried out remotely without user interaction [1].

Impact

Successful exploitation results in arbitrary code execution within the context of the affected library, potentially granting the attacker full control over the device. The impact includes complete compromise of confidentiality, integrity, and availability of the device and its data [1].

Mitigation

Samsung addressed this vulnerability in the Security Maintenance Release (SMR) for April 2022. Users should update their device firmware to the latest available version via the Samsung Security Update policy [1]. No workaround is available for devices that cannot receive the update.
