CVE-2022-39880 is a high-severity vulnerability affecting Samsung Mobile Devices running Android versions R (11) and S (12) prior to the November 2022 security maintenance release (SMR Nov-2022 Release 1). The vulnerability stems from improper input validation (CWE-20) in the DualOutFocusViewer component, which is likely a system-level service or application responsible for camera or image processing features involving dual focus capabilities. Due to insufficient validation of input data, a local attacker with access to the device can exploit this flaw to execute arbitrary code. The vulnerability does not require any privileges (PR:N) or user interaction (UI:N) to be exploited, but it does require local access (AV:L), meaning the attacker must have physical or logical access to the device. The CVSS v3.1 base score is 7.1 (high), with the impact vector indicating no confidentiality or integrity impact but a high impact on availability (A:H). The scope is changed (S:C), meaning the vulnerability affects components beyond the initially vulnerable component, potentially allowing code execution in a different security context. No known exploits are reported in the wild, and no official patch links are provided in the source data, but the vulnerability is addressed in the November 2022 SMR update. The vulnerability's technical root cause is improper input validation, which can lead to memory corruption or logic errors enabling code execution. Given the local access requirement, exploitation scenarios may involve malicious apps, compromised peripherals, or physical access by attackers. The absence of user interaction lowers the barrier for exploitation once local access is obtained.

For European organizations, the impact of CVE-2022-39880 primarily concerns the availability of Samsung mobile devices used within corporate environments. Since the vulnerability allows arbitrary code execution locally without user interaction or privileges, attackers with device access could disrupt device functionality, potentially causing denial of service or enabling further local attacks. This could affect employees relying on Samsung devices for communication, authentication, or access to corporate resources, leading to operational disruptions. Although confidentiality and integrity impacts are not directly indicated, arbitrary code execution could be leveraged in chained attacks to escalate privileges or exfiltrate data if combined with other vulnerabilities. The requirement for local access limits remote exploitation risk but does not eliminate insider threats or risks from lost/stolen devices. Organizations with mobile device management (MDM) policies that include Samsung devices should be aware of this vulnerability, especially in sectors with high security requirements such as finance, government, and critical infrastructure. The lack of known exploits reduces immediate risk, but the presence of a high-severity vulnerability in widely used devices necessitates prompt mitigation to prevent potential exploitation.

1. Immediate deployment of the November 2022 Samsung Mobile Security Maintenance Release (SMR) update on all affected devices to remediate the vulnerability. 2. Enforce strict physical security controls to prevent unauthorized local access to devices, including secure storage and device lock policies. 3. Implement robust mobile device management (MDM) solutions to monitor device compliance, remotely enforce updates, and detect anomalous behavior indicative of exploitation attempts. 4. Restrict installation of untrusted or unsigned applications to reduce the risk of local malicious apps exploiting the vulnerability. 5. Educate users on the risks of connecting devices to untrusted peripherals or networks that could facilitate local attack vectors. 6. Regularly audit and inventory Samsung devices within the organization to ensure all are updated and compliant with security policies. 7. For high-risk environments, consider additional endpoint protection solutions capable of detecting abnormal process behavior resulting from exploitation attempts. 8. Coordinate with Samsung support channels for any additional patches or advisories related to this vulnerability.
