CVE-2025-23107 is a high-severity vulnerability identified in Samsung's Mobile Processor Exynos 1480 and 2400 series. The root cause of this vulnerability is a lack of proper length checking during memory operations, which leads to out-of-bounds writes (CWE-787). Out-of-bounds write vulnerabilities occur when a program writes data outside the boundaries of allocated memory buffers, potentially overwriting adjacent memory. This can lead to unpredictable behavior including data corruption, crashes, or the execution of arbitrary code. The vulnerability has a CVSS v3.1 base score of 8.6, indicating a high impact with the following vector: Network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction needed (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), low integrity impact (I:L), and low availability impact (A:L). This means an attacker can remotely exploit this vulnerability without authentication or user interaction, primarily compromising confidentiality with some impact on integrity and availability. The affected components are embedded within Samsung's Exynos 1480 and 2400 mobile processors, which are widely used in Samsung smartphones and potentially other mobile devices. Although no known exploits are currently reported in the wild, the vulnerability's characteristics make it a significant risk if weaponized. The lack of patch information suggests that mitigation or firmware updates may not yet be available or publicly disclosed. Given the nature of the vulnerability, exploitation could allow attackers to execute arbitrary code or access sensitive data residing in memory, leading to potential device compromise or data leakage. This is particularly critical for mobile devices that handle personal, financial, and corporate information.

For European organizations, the impact of CVE-2025-23107 could be substantial, especially those relying on Samsung mobile devices for business operations, communications, or as part of their mobile workforce. The vulnerability could be exploited to gain unauthorized access to confidential information stored or processed on affected devices, including emails, corporate apps, and authentication tokens. This could lead to data breaches, intellectual property theft, or unauthorized surveillance. Additionally, compromised devices could serve as entry points into corporate networks, facilitating lateral movement or further attacks. The high confidentiality impact combined with remote exploitability without user interaction increases the risk profile. Organizations in sectors such as finance, healthcare, government, and critical infrastructure are particularly vulnerable due to the sensitive nature of their data and regulatory requirements under GDPR and other data protection laws. Furthermore, the potential for device instability or denial of service, although lower, could disrupt business continuity. The lack of available patches at the time of disclosure necessitates immediate risk assessment and interim protective measures.

1. Immediate inventory and identification of devices using Samsung Exynos 1480 and 2400 processors within the organization to understand exposure. 2. Restrict network exposure of vulnerable devices by implementing network segmentation and firewall rules to limit inbound connections, especially from untrusted networks. 3. Employ mobile device management (MDM) solutions to enforce security policies, monitor device behavior, and push updates as they become available. 4. Encourage users to avoid connecting to untrusted or public Wi-Fi networks and use VPNs to secure communications. 5. Monitor security advisories from Samsung and related vendors for firmware or software patches addressing this vulnerability and prioritize timely deployment once available. 6. Implement endpoint detection and response (EDR) tools capable of detecting anomalous behavior indicative of exploitation attempts on mobile devices. 7. Educate users about the risks and signs of device compromise to enhance early detection and reporting. 8. Consider temporary use of alternative devices or platforms for high-risk users until patches are released. 9. Collaborate with mobile security vendors to explore advanced mitigation techniques such as application sandboxing or runtime memory protection.
