CVE-2025-57838 is a vulnerability classified under CWE-200, indicating an exposure of sensitive information to unauthorized actors within Honor's MagicOS operating system. MagicOS is the proprietary OS used on Honor smartphones and related devices. This vulnerability allows an attacker with local access to the device to obtain sensitive information without requiring any privileges or user interaction. The CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) reflects that the attack vector is local, with low attack complexity, no privileges required, and no user interaction needed. The scope remains unchanged, and the impact is limited to confidentiality, with no impact on integrity or availability. The vulnerability was reserved in August 2025 and published in October 2025, with no known exploits in the wild or patches currently available. The lack of required privileges or user interaction means that any unauthorized local user or malware with local execution capabilities could potentially extract sensitive data from the device, which could include personal information, credentials, or other confidential data stored or processed by MagicOS. This vulnerability poses a risk especially in scenarios where devices might be lost, stolen, or accessed by malicious insiders or malware with local execution capabilities.

For European organizations, the primary impact of CVE-2025-57838 lies in the potential exposure of sensitive information stored on or processed by Honor devices running MagicOS. This could lead to confidentiality breaches affecting personal data, corporate credentials, or proprietary information. Although the vulnerability does not affect integrity or availability, the leakage of sensitive data could facilitate further attacks such as identity theft, corporate espionage, or targeted phishing campaigns. The requirement for local access limits the attack surface, but in environments where devices are shared, lost, or physically accessible to unauthorized personnel, the risk increases. Organizations relying on Honor devices for communication or data storage should be aware of this risk, especially in sectors handling sensitive or regulated data such as finance, healthcare, and government. The absence of known exploits reduces immediate risk but does not eliminate the threat, particularly as attackers may develop exploits once the vulnerability becomes public knowledge.

1. Restrict physical and logical local access to Honor devices running MagicOS by enforcing strict device usage policies and access controls. 2. Employ full-disk encryption and strong device authentication mechanisms to reduce the risk of unauthorized local data access. 3. Monitor devices for signs of unauthorized access or malware that could exploit local vulnerabilities. 4. Educate users on the importance of safeguarding their devices from loss or theft. 5. Maintain an inventory of all Honor devices in use and track their security status. 6. Apply security updates and patches from Honor promptly once they become available to address this vulnerability. 7. Consider deploying mobile device management (MDM) solutions that can enforce security policies and remotely wipe compromised devices. 8. Limit the installation of untrusted applications that could gain local execution capabilities and exploit the vulnerability. 9. Conduct regular security assessments and penetration tests focusing on mobile device security within the organization.
