CVE-2025-22409 is a vulnerability identified in Google Android version 15, specifically within the function rfc_send_buf_uih in the source file rfc_ts_frames.cc. The flaw is a use-after-free condition, which occurs when the program continues to use a pointer after the memory it points to has been freed. This can lead to arbitrary code execution within the context of the affected process. The vulnerability allows for local elevation of privilege, meaning an attacker who already has some level of access to the device can exploit this flaw to gain higher privileges, potentially system-level access. Notably, exploitation does not require any additional execution privileges beyond local access, nor does it require user interaction, making it a particularly dangerous vulnerability. The absence of a CVSS score suggests that the vulnerability is newly disclosed and has not yet been fully assessed in terms of severity. There are no known exploits in the wild at the time of publication, and no patches or mitigation links have been provided yet. The vulnerability arises from improper memory management in the Android Bluetooth RFCOMM stack, which handles serial port emulation over Bluetooth, indicating that the attack surface includes Bluetooth functionality on Android devices running version 15.

For European organizations, this vulnerability poses a significant risk, especially for those relying heavily on Android devices for business operations, including mobile workforce, BYOD policies, and IoT deployments. An attacker with local access—such as a malicious insider, an attacker who has compromised a lower-privilege app, or someone with physical access to the device—could exploit this flaw to escalate privileges and gain control over the device. This could lead to unauthorized access to sensitive corporate data, interception of communications, installation of persistent malware, or lateral movement within enterprise networks. Given that user interaction is not required, the attack can be stealthy and automated. The Bluetooth-related nature of the vulnerability could also be exploited remotely in scenarios where Bluetooth is enabled and discoverable, increasing the attack surface. This is particularly concerning for sectors with high security requirements such as finance, healthcare, government, and critical infrastructure within Europe. The lack of a patch at the time of disclosure means organizations must act quickly to mitigate risk through other controls.

1. Immediately audit and restrict local access to Android devices, enforcing strict device usage policies and limiting physical access to trusted personnel only. 2. Disable Bluetooth functionality on Android 15 devices where it is not required, or configure Bluetooth to non-discoverable mode to reduce exposure. 3. Employ Mobile Device Management (MDM) solutions to monitor device behavior and enforce security policies, including application whitelisting and privilege restrictions. 4. Monitor for unusual privilege escalations or anomalous behavior on Android devices, using endpoint detection and response (EDR) tools tailored for mobile platforms. 5. Educate users and administrators about the risks of local privilege escalation vulnerabilities and the importance of promptly applying security updates once patches become available. 6. Coordinate with Google and Android device vendors to obtain and deploy security patches as soon as they are released. 7. Consider network segmentation to isolate mobile devices from critical systems to limit potential lateral movement if a device is compromised.
