CVE-2025-48647 is a vulnerability identified in the cpm_fwtp_msg_handler function within the cpm/google/lib/tracepoint/cpm_fwtp_ipc.c source code of Google Devices. The root cause is improper input validation, which can lead to a memory overwrite condition. This memory corruption flaw enables a local attacker, who already has limited execution privileges on the device, to escalate their privileges without requiring additional execution rights or user interaction. The vulnerability is classified under CWE-20 (Improper Input Validation), indicating that the software does not adequately verify input data before processing it, leading to unsafe memory operations. The CVSS v3.1 base score is 7.8, reflecting a high severity due to the combined impact on confidentiality, integrity, and availability, ease of exploitation with low attack complexity, and no user interaction needed. Although no exploits are currently known in the wild and no patches have been published, the vulnerability poses a significant risk to the security posture of affected Google Devices. The flaw could be exploited by malicious local users or malware that gains limited access, allowing them to gain elevated privileges and potentially compromise the entire device or network. The absence of affected version details suggests the vulnerability may impact multiple or all versions of Google Devices firmware or software components using this code path.

For European organizations, the impact of CVE-2025-48647 could be substantial, particularly in sectors relying heavily on Google Devices for communication, collaboration, or IoT deployments. Successful exploitation would allow attackers to escalate privileges locally, potentially leading to full device compromise, unauthorized access to sensitive data, disruption of device functionality, and lateral movement within corporate networks. This could result in data breaches, operational downtime, and damage to organizational reputation. Given the vulnerability does not require user interaction, automated or stealthy attacks become feasible once local access is obtained, increasing the risk in environments with shared or poorly controlled device access. Critical infrastructure, government agencies, and enterprises using Google Devices in Europe may face heightened risks, especially if these devices are integrated into security-sensitive workflows or handle confidential information.

To mitigate CVE-2025-48647, European organizations should implement the following specific measures: 1) Monitor official Google security advisories closely and apply patches or firmware updates immediately once released. 2) Restrict local device access to trusted personnel only, employing strong authentication and physical security controls to prevent unauthorized local access. 3) Employ endpoint detection and response (EDR) solutions capable of identifying anomalous memory operations or privilege escalation attempts on Google Devices. 4) Use application whitelisting and privilege management to limit the execution of untrusted code that could exploit this vulnerability. 5) Conduct regular security audits and penetration testing focused on local privilege escalation vectors in Google Devices. 6) Segment networks to isolate Google Devices from critical systems, reducing potential lateral movement. 7) Educate users and administrators about the risks of local privilege escalation and enforce strict device usage policies. These targeted actions go beyond generic advice by focusing on controlling local access and monitoring for exploitation attempts specific to this vulnerability.
