CVE-2025-47365

7.8 HIGH

📋 TL;DR

This vulnerability allows remote attackers to cause memory corruption by sending large input data through a communication interface. It affects systems using Qualcomm components that process untrusted input from network sources. Successful exploitation could lead to denial of service or arbitrary code execution.

💻 Affected Systems

Products:
  • Qualcomm chipsets and components
Versions: Specific versions not detailed in reference; check Qualcomm advisory for affected products.
Operating Systems: Android, embedded systems using Qualcomm components
Default Config Vulnerable: ⚠️ Yes
Notes: Affects systems with Qualcomm hardware that process network data; exact product list requires checking vendor advisory.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution leading to complete system compromise and potential lateral movement within the network.

🟠

Likely Case

Denial of service causing system crashes or instability when processing malicious input.

🟢

If Mitigated

Limited impact with proper input validation and memory protection mechanisms in place.

🌐 Internet-Facing: HIGH - Remote exploitation possible via communication interfaces exposed to untrusted networks.
🏢 Internal Only: MEDIUM - Requires network access but could be exploited internally via lateral movement.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: MEDIUM

Exploitation requires crafting specific large input data but no authentication needed.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Qualcomm November 2025 security bulletin for specific patches

Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/november-2025-bulletin.html

Restart Required: Yes

Instructions:

1. Review Qualcomm November 2025 security bulletin. 2. Identify affected components in your system. 3. Apply firmware/software updates from device manufacturer. 4. Reboot affected systems.

🔧 Temporary Workarounds

Input validation and size limits

all

Implement strict input validation and size limits on communication interfaces

Network segmentation

all

Restrict network access to affected communication interfaces

🧯 If You Can't Patch

  • Implement strict network filtering and firewall rules to limit access to vulnerable interfaces
  • Deploy intrusion detection systems to monitor for exploitation attempts

🔍 How to Verify

Check if Vulnerable:

Check system firmware/software versions against Qualcomm advisory; systems using affected Qualcomm components are vulnerable.

Check Version:

System-specific commands vary; check device manufacturer documentation for version checking.

Verify Fix Applied:

Verify firmware/software has been updated to versions listed in Qualcomm security bulletin as patched.

📡 Detection & Monitoring

Log Indicators:

  • System crashes, memory allocation errors, abnormal process termination related to communication interfaces

Network Indicators:

  • Unusually large data packets sent to communication interfaces, repeated connection attempts with malformed data

SIEM Query:

source="network_logs" AND (packet_size>threshold OR pattern="malformed_input")
