CVE-2025-22408 is a critical remote code execution (RCE) vulnerability affecting Google Android version 15. The flaw exists in the function rfc_check_send_cmd within the rfc_utils.cc source file, where a use-after-free condition can occur. This vulnerability allows an attacker to execute arbitrary code on the affected device without requiring any additional privileges or user interaction. The root cause is a use-after-free (CWE-416) error, which means that the program continues to use memory after it has been freed, potentially leading to memory corruption and arbitrary code execution. The vulnerability is exploitable remotely over the network (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H), making this a critical security issue. Although no known exploits are currently reported in the wild, the high CVSS score of 9.8 indicates that this vulnerability poses a severe threat to Android devices running version 15. The absence of patches at the time of publication increases the urgency for mitigation and monitoring. Given the widespread use of Android devices globally, this vulnerability could be leveraged by attackers to gain full control over affected devices remotely, potentially leading to data theft, device manipulation, or denial of service.

For European organizations, the impact of CVE-2025-22408 could be substantial due to the widespread adoption of Android devices in both consumer and enterprise environments. Organizations relying on Android 15 devices for communication, mobile workforce operations, or IoT integrations could face significant risks including unauthorized access to sensitive corporate data, disruption of business operations, and potential lateral movement within networks if compromised devices are connected to internal systems. The fact that exploitation requires no user interaction and no privileges means that attackers could silently compromise devices, making detection and prevention more challenging. Critical sectors such as finance, healthcare, government, and telecommunications in Europe could be particularly vulnerable due to the sensitive nature of their data and services. Additionally, the potential for remote exploitation increases the risk of large-scale attacks or targeted campaigns against high-value targets within Europe.

Given the critical nature of this vulnerability and the lack of an official patch at the time of reporting, European organizations should implement immediate and specific mitigation strategies beyond generic advice: 1) Network-level protections: Employ advanced intrusion detection and prevention systems (IDS/IPS) capable of detecting anomalous traffic patterns associated with exploitation attempts targeting Android devices. 2) Device management: Enforce strict mobile device management (MDM) policies to control which Android 15 devices can connect to corporate networks and limit their access based on risk assessments. 3) Segmentation: Isolate Android devices from critical internal systems and sensitive data repositories to reduce the attack surface and limit potential lateral movement. 4) Monitoring and logging: Enhance monitoring of Android device behavior and network traffic for signs of exploitation, including unusual command execution or memory corruption indicators. 5) User awareness: Although no user interaction is required, educating users about the risks and encouraging prompt reporting of unusual device behavior can aid early detection. 6) Vendor engagement: Maintain close communication with Google and Android device manufacturers to receive timely updates and apply patches as soon as they become available. 7) Temporary workarounds: If feasible, disable or restrict the vulnerable functionality (rfc_check_send_cmd) through configuration or application controls until a patch is released.
