CVE-2025-22404 is a high-severity local privilege escalation vulnerability affecting Google Android version 15. The flaw exists in the Bluetooth AVCT (Audio/Video Control Transport) protocol implementation, specifically within the avct_lcb_msg_ind function of the avct_lcb_act.cc source file. The vulnerability is caused by a use-after-free condition (CWE-416), where memory is accessed after it has been freed, potentially allowing an attacker to execute arbitrary code within the context of a privileged process. This vulnerability does not require any user interaction or prior execution privileges, meaning an attacker with local access to the device can exploit it directly to escalate their privileges. The CVSS v3.1 base score is 8.4, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no privileges or user interaction required. Although no known exploits are currently reported in the wild, the nature of the vulnerability and its presence in a widely used mobile OS make it a significant threat. The lack of an official patch link suggests that remediation may still be pending or in progress. The vulnerability could be exploited by malicious applications or local attackers to gain elevated privileges, potentially leading to full device compromise, unauthorized access to sensitive data, or persistent malware installation.

For European organizations, this vulnerability poses a substantial risk, especially those relying heavily on Android 15 devices for business operations, including mobile workforce, BYOD environments, and IoT deployments. Exploitation could allow attackers to bypass Android's sandboxing and permission models, leading to unauthorized access to corporate data, interception of communications, and disruption of services. The ability to escalate privileges without user interaction increases the risk of stealthy attacks and automated exploitation. This could impact sectors such as finance, healthcare, government, and critical infrastructure where mobile device security is paramount. Additionally, compromised devices could serve as entry points into corporate networks, facilitating lateral movement and broader cyberattacks. The absence of known exploits currently provides a window for proactive mitigation, but the high severity score underscores the urgency for organizations to address this vulnerability promptly.

European organizations should implement a multi-layered mitigation strategy beyond generic patching advice. First, they should inventory and identify all Android 15 devices in use, prioritizing those with access to sensitive corporate resources. Until an official patch is available, organizations should enforce strict application control policies, restricting installation of untrusted or unnecessary apps that could exploit this vulnerability. Employ Mobile Threat Defense (MTD) solutions capable of detecting anomalous Bluetooth activity or exploitation attempts targeting AVCT components. Network segmentation and limiting Bluetooth usage in sensitive environments can reduce exposure. Encourage users to disable Bluetooth when not in use and avoid connecting to untrusted devices. Implement endpoint detection and response (EDR) tools with mobile capabilities to monitor for signs of privilege escalation or suspicious behavior. Once patches are released, deploy them rapidly through mobile device management (MDM) platforms. Finally, conduct user awareness training emphasizing the risks of local exploitation and the importance of device hygiene.
