Overview
CVE-2025-48558 is a high-severity vulnerability that targets the BatteryService.java functions. The vulnerability arises from the potential hijacking of implicit intent intended for system apps. Cybercriminals could exploit this vulnerability to escalate their privileges locally without the need for additional execution privileges or user interaction. The threat of system compromise or data leakage is a significant concern for businesses and individuals.

How the Exploit Works
The vulnerability resides in multiple functions of BatteryService.java. The flaw can lead to an implicit intent hijacking due to incorrect handling of certain system-level operations. An attacker exploiting this vulnerability can intercept and manipulate these implicit intents to escalate their privileges within the system. This can be done without any additional execution privileges and does not require user interaction.
Conceptual Example Code
The following pseudocode provides a conceptual example of how the vulnerability could be exploited:
Intent maliciousIntent = new Intent();
maliciousIntent.setFlags(Intent.FLAG_RECEIVER_FOREGROUND);
maliciousIntent.setComponent(new ComponentName("com.system.app","com.system.app.Receiver"));
Bundle maliciousBundle = new Bundle();
maliciousBundle.putString("extra_key","malicious_value");
maliciousIntent.putExtras(maliciousBundle);
context.sendBroadcast(maliciousIntent);In this example, the attacker creates a malicious intent, sets it as a foreground receiver, and uses it to target a system app’s receiver. The malicious intent contains an extra bundle with a malicious value that could be used to cause unexpected behavior in the targeted system app.
Mitigation Guidance
The primary mitigation method for this vulnerability is to apply the vendor patch as soon as it becomes available. In the meantime, or if a patch is not yet available, temporary mitigation can be achieved by using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block potential exploit attempts.
