CVE-2025-48558 is a local privilege escalation vulnerability affecting multiple versions of the Google Android operating system, specifically versions 13 through 16. The vulnerability arises from improper handling of implicit intents within the BatteryService.java component. Implicit intents in Android are messages that allow components to request actions from other components without specifying the exact target, relying instead on the system to resolve the appropriate recipient. In this case, the vulnerability allows an attacker to hijack these implicit intents that are intended for system-level applications. By intercepting or redirecting these intents, an attacker can execute code or commands with elevated privileges without requiring any additional execution privileges or user interaction. This means that a malicious app or process running on the device can exploit this flaw to escalate its privileges locally, potentially gaining access to sensitive system functions or data that should be restricted. The exploitation does not require the attacker to trick the user into performing any action, making it more dangerous as it can be triggered silently. Although no known exploits in the wild have been reported yet, the vulnerability's nature and the affected Android versions suggest a significant risk, especially as Android 13 to 16 are widely deployed in modern devices. The lack of a CVSS score indicates that the vulnerability is newly published and has not yet undergone formal severity assessment. However, the technical details confirm that the flaw is due to implicit intent hijacking, a well-known attack vector in Android security, which can lead to unauthorized privilege escalation.

For European organizations, this vulnerability poses a considerable risk, especially those relying heavily on Android devices for business operations, including mobile workforce management, secure communications, and access to corporate resources. An attacker exploiting this vulnerability could gain elevated privileges on affected devices, potentially bypassing security controls, accessing sensitive corporate data, or installing persistent malware. This could lead to data breaches, unauthorized access to internal networks, and disruption of business processes. Given that no user interaction is required, the risk of silent compromise increases, making detection and prevention more challenging. Organizations in sectors such as finance, healthcare, government, and critical infrastructure, which often have stringent data protection requirements under regulations like GDPR, could face severe compliance and reputational consequences if devices are compromised. Additionally, the widespread use of Android devices in Europe means that the attack surface is large, and the potential for lateral movement within corporate networks exists if compromised devices are connected to internal systems.

To mitigate this vulnerability, European organizations should prioritize the following actions: 1) Immediate patch management: Monitor Google and device manufacturers for security updates addressing CVE-2025-48558 and deploy patches promptly to all affected Android devices. 2) Application control: Restrict installation of untrusted or unnecessary applications, especially those requesting elevated permissions or capable of intercepting intents. 3) Device hardening: Employ Mobile Device Management (MDM) solutions to enforce security policies, including restricting background app activities and controlling intent handling where possible. 4) Network segmentation: Isolate mobile devices from critical internal networks to limit potential lateral movement in case of compromise. 5) Monitoring and detection: Implement endpoint detection and response (EDR) tools capable of identifying suspicious privilege escalation behaviors on Android devices. 6) User education: Although exploitation does not require user interaction, educating users on safe device usage and recognizing unusual device behavior can aid early detection. 7) Incident response readiness: Prepare and test incident response plans specifically for mobile device compromise scenarios to ensure swift containment and remediation.
