CVE-2025-52512 identifies a race condition vulnerability in the HTS driver of Samsung Mobile Processor models Exynos 2400, 1580, and 2500. A race condition occurs when multiple threads or processes access shared resources concurrently without proper synchronization, leading to unpredictable behavior. In this case, the race condition causes out-of-bounds memory access, which can corrupt memory and cause the system or device to crash, resulting in a denial of service (DoS). The vulnerability is located at the driver level, which is a critical component managing hardware interactions. Exploiting this flaw likely requires local access to the device, as the HTS driver is part of the mobile processor's internal software stack. No CVSS score has been assigned yet, and no patches or known exploits have been reported as of the publication date. The affected processors are widely deployed in Samsung smartphones, which are prevalent in consumer and enterprise environments. The vulnerability could be leveraged by attackers to disrupt device availability, potentially impacting user productivity and critical communications. The lack of authentication or user interaction requirements simplifies exploitation scenarios, especially if an attacker gains physical or local access to the device. This vulnerability underscores the importance of timely patching and secure driver development practices in mobile hardware platforms.

The primary impact of CVE-2025-52512 is denial of service, which affects device availability by causing crashes or system instability. For European organizations, this could disrupt mobile communications, especially in sectors relying heavily on Samsung smartphones for secure and continuous connectivity, such as finance, healthcare, and government. The vulnerability could be exploited by insiders or attackers with local access to devices, potentially leading to targeted disruptions. While confidentiality and integrity impacts are not indicated, the loss of availability can have cascading effects on operational continuity and user trust. Organizations with mobile device management (MDM) systems may face challenges if large numbers of devices become unstable or unusable. The absence of known exploits reduces immediate risk but also means organizations must be proactive in monitoring and patching. The impact is heightened in environments where mobile devices serve as critical endpoints for multi-factor authentication or secure communications.

1. Monitor Samsung's official security advisories and promptly apply any patches or firmware updates addressing this vulnerability. 2. Implement strict access controls to limit physical and local access to devices running affected Exynos processors. 3. Use mobile device management (MDM) solutions to enforce security policies and remotely manage device updates. 4. Restrict installation of untrusted applications that could exploit local vulnerabilities. 5. Educate users about the risks of connecting to untrusted networks or installing unauthorized software. 6. In sensitive environments, consider temporary use of alternative devices or processors until patches are available. 7. Conduct regular security audits and vulnerability assessments on mobile device fleets. 8. Collaborate with Samsung and security vendors for threat intelligence updates related to this vulnerability.
