CVE-2025-23104 is a security vulnerability identified in the Samsung Mobile Processor Exynos 2200, specifically characterized as a Use-After-Free (CWE-416) flaw. This type of vulnerability occurs when a program continues to use a pointer after the memory it points to has been freed, potentially leading to undefined behavior including privilege escalation. In this case, the flaw allows an attacker to escalate privileges on the affected mobile processor without requiring any user interaction or prior authentication. The CVSS 3.1 base score is 6.5, indicating a medium severity level. The vector metrics specify that the attack can be launched remotely over the network (AV:N), requires low attack complexity (AC:L), no privileges (PR:N), and no user interaction (UI:N). The impact affects confidentiality and integrity but not availability (C:L/I:L/A:N). Although no known exploits are currently reported in the wild, the vulnerability presents a significant risk because it enables attackers to gain elevated privileges on devices powered by the Exynos 2200 processor. This could allow attackers to bypass security controls, access sensitive data, or execute arbitrary code at a higher privilege level. The lack of available patches or mitigations at the time of publication increases the urgency for affected parties to monitor for updates and implement compensating controls. The vulnerability’s presence in a widely deployed mobile processor used in Samsung smartphones and potentially other devices means the attack surface is broad, especially in regions with high Samsung device market share.

For European organizations, the impact of CVE-2025-23104 could be significant, particularly for enterprises and government agencies that rely on Samsung mobile devices for communication and operational purposes. Privilege escalation on mobile processors can lead to unauthorized access to corporate data, interception of communications, and potential lateral movement within internal networks if mobile devices are used as entry points. Confidentiality and integrity of sensitive information could be compromised, affecting compliance with GDPR and other data protection regulations. Additionally, the inability to immediately patch the vulnerability may expose organizations to targeted attacks exploiting this flaw. The risk is heightened for sectors with high security requirements such as finance, healthcare, and critical infrastructure, where mobile device security is integral to overall cybersecurity posture. Furthermore, the vulnerability could be leveraged in espionage or cybercrime campaigns targeting European entities, given the strategic importance of mobile communications in modern operations.

Given the absence of patches at the time of disclosure, European organizations should adopt a multi-layered mitigation strategy. First, they should inventory and identify all devices using the Exynos 2200 processor to assess exposure. Network-level protections such as strict firewall rules and intrusion detection/prevention systems should be configured to monitor and block suspicious traffic targeting mobile devices. Employ Mobile Device Management (MDM) solutions to enforce security policies, restrict installation of untrusted applications, and enable remote wipe capabilities. Organizations should also educate users about the risks and encourage cautious behavior regarding app installations and network connections. Monitoring for unusual device behavior or privilege escalations can help detect exploitation attempts early. Once patches or firmware updates become available from Samsung, organizations must prioritize rapid deployment. Collaboration with device vendors and security communities to share threat intelligence related to this vulnerability will further enhance defenses. Finally, consider isolating critical mobile devices or limiting their access to sensitive systems until the vulnerability is mitigated.
