CVE-2025-52910 is a Use-After-Free (CWE-416) vulnerability discovered in the GPU components of several Samsung Exynos processors, specifically models 1280, 2200, 1330, 1380, 1480, and 2400, which are widely used in Samsung mobile phones and wearable devices. The vulnerability arises from improper memory management in the GPU driver or firmware, where a freed memory object is accessed again, leading to undefined behavior. This flaw can be exploited by an attacker to escalate privileges on the device, granting them higher-level access than intended. The CVSS v3.1 base score of 9.8 reflects the vulnerability's critical nature, with attack vector being network-based (AV:N), no required privileges (PR:N), no user interaction (UI:N), and full impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Exploitation does not require authentication or user interaction, making it highly dangerous. Although no public exploits are currently known, the vulnerability's characteristics suggest that attackers could develop reliable exploits to gain control over affected devices. The lack of available patches at the time of publication increases the urgency for Samsung and users to address this issue promptly. The vulnerability could be leveraged to bypass security controls, access sensitive information, install persistent malware, or disrupt device functionality.

For European organizations, the impact of CVE-2025-52910 is significant due to the widespread use of Samsung devices powered by the affected Exynos processors. Privilege escalation on mobile and wearable devices can lead to unauthorized access to corporate networks, sensitive communications, and personal data. This is especially critical for sectors such as finance, healthcare, government, and critical infrastructure, where mobile device security is paramount. The ability to escalate privileges without user interaction or authentication increases the risk of automated or remote attacks, potentially enabling espionage, data theft, or sabotage. Additionally, compromised devices could serve as entry points for lateral movement within enterprise networks. The vulnerability also threatens the integrity and availability of devices, potentially causing operational disruptions. Given the high CVSS score and critical severity, organizations must consider this vulnerability a top priority for risk management and incident response planning.

1. Monitor Samsung’s official security advisories and apply firmware or software patches immediately once released. 2. Until patches are available, restrict GPU access on devices through mobile device management (MDM) policies to limit exposure. 3. Employ endpoint detection and response (EDR) solutions capable of monitoring unusual privilege escalation attempts or GPU-related anomalies. 4. Enforce strict application whitelisting and sandboxing to reduce the attack surface on mobile devices. 5. Educate users about the risks and encourage prompt installation of updates. 6. For organizations deploying Samsung devices, consider network segmentation and zero-trust principles to contain potential compromises. 7. Collaborate with device vendors to obtain timely updates and verify patch effectiveness. 8. Conduct regular security assessments and penetration testing focusing on mobile device security posture. 9. Implement strong authentication and encryption to protect sensitive data even if device integrity is compromised. 10. Prepare incident response plans specifically addressing mobile device compromise scenarios.
