CVE-2025-48611

Comprehensive Technical Analysis of CVE-2025-48611

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-48611 CVSS Score: 10

The vulnerability in question, CVE-2025-48611, is classified as a critical security flaw with a CVSS score of 10, the highest possible rating. This indicates a severe risk to affected systems. The vulnerability is located in the DeviceId class of DeviceId.java, where a missing bounds check can lead to a desynchronization in persistence. This flaw can be exploited to achieve local escalation of privilege without requiring additional execution privileges or user interaction.

2. Potential Attack Vectors and Exploitation Methods

The primary attack vector for this vulnerability is local exploitation. An attacker with local access to the device can exploit the missing bounds check to manipulate the persistence mechanism, leading to a desynchronization. This desynchronization can be leveraged to escalate privileges, potentially gaining unauthorized access to sensitive data or system functionalities.

Exploitation Methods:

• Bounds Check Bypass: The attacker can craft specific inputs that bypass the missing bounds check, causing the persistence mechanism to desynchronize.
• Privilege Escalation: Once the desynchronization occurs, the attacker can exploit this state to elevate their privileges, gaining access to higher-level system functions or data.

3. Affected Systems and Software Versions

The vulnerability affects Android devices, specifically those running versions of the Android operating system that include the flawed DeviceId.java class. The exact versions are not specified in the provided information, but it is likely to impact a broad range of Android devices, particularly those that have not received the latest security patches.

4. Recommended Mitigation Strategies

Immediate Mitigation:

• Apply Security Patches: Ensure that all affected devices are updated with the latest security patches provided by the vendor. This is the most effective way to mitigate the risk.
• Limit Local Access: Restrict physical and local access to devices to trusted users only.

Long-Term Mitigation:

• Regular Security Audits: Conduct regular security audits and code reviews to identify and fix similar vulnerabilities.
• Implement Bounds Checking: Ensure that all code handling persistence mechanisms includes proper bounds checking to prevent desynchronization.

5. Impact on Cybersecurity Landscape

The discovery of CVE-2025-48611 highlights the ongoing challenge of securing mobile devices, particularly those running the Android operating system. The high CVSS score underscores the potential for significant damage if exploited, including data breaches, unauthorized access, and system compromise. This vulnerability serves as a reminder of the importance of timely patching and the need for robust security measures in mobile device management.

6. Technical Details for Security Professionals

Vulnerability Details:

• Location: DeviceId class in DeviceId.java
• Issue: Missing bounds check leading to desynchronization in persistence
• Exploitation: Local privilege escalation without additional execution privileges or user interaction

Detection and Response:

• Monitoring: Implement monitoring tools to detect unusual activity that may indicate an attempt to exploit this vulnerability.
• Incident Response: Develop and maintain an incident response plan that includes steps for identifying, containing, and remediating exploitation attempts.

Code Review:

• Bounds Checking: Ensure that all code handling data persistence includes proper bounds checking to prevent similar vulnerabilities.
• Static Analysis: Use static analysis tools to identify potential issues in the codebase, such as missing bounds checks.

Conclusion: CVE-2025-48611 represents a critical vulnerability in Android devices that requires immediate attention. By applying the recommended mitigation strategies and maintaining vigilant security practices, organizations can significantly reduce the risk posed by this vulnerability. Regular updates, security audits, and robust incident response plans are essential components of a comprehensive cybersecurity strategy.
