Summary
by MITRE • 03/10/2026
In DeviceId of DeviceId.java, there is a possible desync in persistence due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

The vulnerability identified as CVE-2025-48611 resides within the DeviceId component of DeviceId.java, representing a critical security flaw that undermines the integrity of device identification mechanisms. This issue manifests as a desynchronization in persistence states, where the system fails to properly validate input boundaries before processing device identifiers. The absence of proper bounds checking creates a condition where malicious actors can manipulate device identification data without requiring any additional privileges or user interaction to initiate exploitation. The vulnerability specifically targets the persistence layer of device identification, potentially allowing attackers to maintain unauthorized access or manipulate device states across system restarts or reboots.
The technical implementation flaw stems from inadequate input validation within the DeviceId.java file, where the system does not perform proper boundary checks on device identifier data before storing or retrieving persistent state information. This missing validation creates a potential buffer overflow condition or memory corruption scenario that could be leveraged to alter device identification parameters in ways that persist beyond normal operational boundaries. The vulnerability operates at the system level where device identifiers are stored and retrieved, making it particularly dangerous as it can affect the core identification mechanisms that many security systems rely upon for access control and device authentication. According to CWE classification, this vulnerability maps to CWE-129: Improper Validation of Array Index, which specifically addresses the lack of proper bounds checking in array or buffer operations.
The operational impact of this vulnerability extends beyond simple privilege escalation to encompass potential system compromise and unauthorized device manipulation. An attacker exploiting this vulnerability can achieve local privilege escalation without requiring additional execution privileges, meaning the attack can be initiated from within the system's own operational environment. This characteristic makes the vulnerability particularly concerning as it can be exploited by malicious processes already running with legitimate system privileges. The lack of user interaction requirements significantly increases the attack surface and reduces the barriers to exploitation, allowing for automated or opportunistic attacks that can persist across system reboots. The vulnerability's persistence mechanism means that even after system restarts or normal operational cycles, the malicious state can be maintained, creating a long-term security risk.
Mitigation strategies for CVE-2025-48611 should focus on implementing comprehensive input validation and bounds checking mechanisms throughout the DeviceId.java component. System administrators should prioritize immediate patching of affected systems and implement monitoring solutions that can detect anomalous device identification patterns or unauthorized modifications to persistent device state information. The remediation process should include thorough code review of all persistence mechanisms within device identification systems, ensuring that proper bounds checking is implemented for all array and buffer operations. Additionally, implementing runtime protections such as stack canaries, address space layout randomization, and data execution prevention measures can provide additional layers of defense against exploitation attempts. Organizations should also conduct comprehensive vulnerability assessments to identify similar patterns in other system components that might be susceptible to the same class of vulnerability, following ATT&CK framework guidance for privilege escalation techniques. The implementation of proper input sanitization and validation procedures should be integrated into all development lifecycle processes to prevent similar vulnerabilities from being introduced in future system updates or modifications.
