CVE-2025-0084 is a critical remote code execution (RCE) vulnerability affecting Google Android versions 13, 14, and 15. The vulnerability arises from a use-after-free condition that leads to an out-of-bounds write in multiple locations within the Bluetooth stack, specifically when Hands-Free Profile (HFP) support is enabled. This flaw allows an attacker to execute arbitrary code remotely without requiring any additional execution privileges or user interaction. The exploitation vector is over Bluetooth, meaning an attacker within wireless range can trigger the vulnerability silently and gain control over the affected device. The lack of need for user interaction significantly increases the risk and ease of exploitation. The vulnerability is particularly dangerous because it compromises the confidentiality, integrity, and availability of the device by enabling full remote code execution, potentially allowing attackers to install malware, exfiltrate data, or disrupt device operations. Although no known exploits are currently reported in the wild, the technical nature of the flaw and its presence in recent Android versions make it a high-priority issue for patching and mitigation.

For European organizations, this vulnerability poses a significant threat due to the widespread use of Android devices in both personal and enterprise environments. The ability to remotely execute code without user interaction over Bluetooth means that attackers could infiltrate corporate networks by compromising employee mobile devices, especially those with Bluetooth enabled and HFP support active. This could lead to unauthorized access to sensitive corporate data, lateral movement within networks, and disruption of business operations. The risk is amplified in sectors with high Bluetooth usage such as automotive, healthcare, and manufacturing, where Android devices often interface with specialized equipment. Additionally, the vulnerability could be exploited in public or semi-public spaces (e.g., offices, cafes, transport hubs), increasing the attack surface. The absence of a patch at the time of disclosure further elevates the urgency for organizations to implement interim protective measures. Given the potential for stealthy exploitation, detection and incident response efforts may be complicated, increasing the likelihood of prolonged undetected compromise.

1. Immediate disabling of Bluetooth on Android devices where HFP support is not essential, especially in high-risk environments. 2. For devices requiring Bluetooth and HFP, enforce strict device usage policies limiting Bluetooth connectivity to trusted devices only, using allowlists and connection monitoring. 3. Deploy Mobile Device Management (MDM) solutions to enforce security configurations and monitor Bluetooth activity for anomalies. 4. Educate users on the risks of leaving Bluetooth enabled in public or untrusted environments. 5. Monitor for unusual device behavior or network traffic that could indicate exploitation attempts. 6. Coordinate with device vendors and Google for timely patch deployment once available, and prioritize patching of all affected Android versions (13, 14, 15). 7. Consider network segmentation and endpoint detection tools that can identify compromised devices to limit lateral movement. 8. Implement Bluetooth firmware and driver updates as they become available, as these may contain critical fixes beyond OS patches.
