⚠️ CRITICAL ⚠️
CVE-2025-48593 - Zero-Click RCE in Android System
"A single malicious packet can own your device."
— Android Security Team, Nov 2025
Vulnerability Summary
This vulnerability is a critical zero-click remote code execution (RCE) flaw in core components of the Android operating system.
An unauthenticated attacker on the same network can exploit this issue by sending a specially crafted packet to a target device, requiring no interaction from the user.
Attribute Details
CVE ID: CVE-2025-48593
Severity: Critical 9.8 (Estimated CVSS)
Attack Vector:
- Network (Remote)
- User Interaction❌ None Required (Zero-Click)
- Privileges❌ None Required
🛡️ Affected Systems
This vulnerability affects most recent Android versions.
Devices are considered vulnerable if they are running a security patch level before November 2025.
Android 13
Android 14
Android 15
Android 16 & (Pre-release and official builds)
Devices that have successfully installed the November 2025 Android Security Update (patch level 2025-11-01 or 2025-11-05) are protected.
⚡ Technical Analysis
The root cause is a classic buffer overflow in a system service that processes incoming network packets.
The vulnerable component fails to properly validate the size of an incoming packet's payload before copying it into a fixed-size buffer in the system's memory.
An attacker can send a packet with a payload larger than the buffer's capacity, overflowing it and overwriting adjacent memory.
This memory corruption can be leveraged to divert the system's execution flow and run arbitrary code with elevated privileges.
Simplified Pseudocode of the Flaw:C// This function in the system service processes packets
void process_system_packet(Packet *p) {
// A fixed-size buffer on the stack or heap
char kernel_buffer[1024];
if (p->type == MALICIOUS_TYPE) {
// ⚠️ VULNERABILITY: No check on p->size
// If p->size > 1024, memory outside
// kernel_buffer is corrupted.
memcpy(kernel_buffer, p->payload, p->size);
execute_payload(); // Attacker's code may run here
}
}
