CVE-2025-48593 Remote Code Execution Zero-Click Exploit

Overview

Google released the November 2025 Android Security Bulletin addressing multiple critical vulnerabilities in the Android platform. The most severe flaw resides in the System component, allowing remote code execution (RCE) without user interaction or additional privileges. This zero-click vulnerability poses a significant risk to unpatched Android devices.

Technical Specifications

Attribute Details
CVE ID CVE-2025-48593 (Primary), CVE-2025-48581
Vulnerability Type Remote Code Execution (RCE), Elevation of Privilege (EoP)
Attack Vector Network (remote)
Authentication None required
Complexity Low
User Interaction Not required (Zero-Click)

Affected Products

  • Android Versions: 13, 14, 15, and 16
  • Components: System component, apexd.cpp
  • Patch Level Required: 2025-11-01 or later
  • Status: Patched in November 2025 Security Update

Attack Scenario
