CVE-2025-48625 is a vulnerability identified in Google Android version 16-qpr2, involving a race condition in multiple locations within the UsbDataAdvancedProtectionHook.java source file. This race condition permits unauthorized access to USB data when the device screen is off, effectively bypassing intended data protection mechanisms. The flaw allows a local attacker to escalate privileges without requiring additional execution privileges or user interaction, which significantly lowers the barrier for exploitation. The vulnerability is categorized under CWE-362, indicating a concurrency issue where improper synchronization leads to unexpected behavior. The vulnerability impacts the confidentiality, integrity, and availability of the device by potentially exposing sensitive USB data and enabling privilege escalation. The CVSS v3.1 score is 7.0 (high), with vector AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating local attack vector, high attack complexity, low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability. No known exploits have been reported in the wild as of the publication date. The vulnerability affects Android devices running version 16-qpr2, which is a recent release, implying that many modern devices could be impacted. The race condition arises from improper handling of concurrent access to USB data protection hooks, allowing attackers to access or manipulate USB data when the screen is off, a state where data access should be restricted. This can lead to unauthorized data exposure and privilege escalation, potentially enabling further compromise of the device.

The vulnerability poses a significant risk to organizations and individual users relying on affected Android devices. Successful exploitation can lead to unauthorized access to sensitive USB data, compromising confidentiality. The elevation of privilege allows attackers to gain higher-level permissions, potentially enabling installation of malicious software, data tampering, or disruption of device operations, impacting integrity and availability. Since exploitation does not require user interaction and can be performed locally, insider threats or malware with limited privileges could leverage this flaw to escalate access. This could facilitate lateral movement within enterprise environments or enable attackers to bypass security controls on mobile devices. The impact extends to any organization that uses Android devices for sensitive communications, data storage, or operational control, including government agencies, financial institutions, healthcare providers, and enterprises with mobile workforces. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the potential for future attacks once exploit code becomes available. The vulnerability also undermines trust in device security, potentially affecting user confidence and compliance with data protection regulations.

Organizations and users should monitor for official patches from Google and apply them promptly once released to address this vulnerability. Until patches are available, restricting physical and local access to Android devices is critical to reduce the risk of exploitation. Implementing device management policies that limit USB debugging and data transfer capabilities when the screen is off can help mitigate exposure. Employing endpoint security solutions that detect unusual local privilege escalation attempts or USB activity anomalies can provide additional defense layers. Regularly auditing device configurations and usage policies to minimize unnecessary privileges and access rights will reduce the attack surface. For enterprise environments, enforcing strong authentication and encryption on mobile devices, along with network segmentation, can limit the impact of a compromised device. Educating users about the risks of connecting unknown USB devices and maintaining updated security awareness programs will further reduce exploitation likelihood. Finally, organizations should prepare incident response plans that include scenarios involving local privilege escalation on mobile devices to ensure rapid containment and remediation.
