CVE-2025-47364
📋 TL;DR
This CVE describes an integer overflow vulnerability (CWE-190) in Qualcomm partition handling that could allow memory corruption when calculating offsets from partition start points. Attackers could potentially exploit this to execute arbitrary code or cause denial of service. The vulnerability affects Qualcomm-based devices including smartphones, IoT devices, and embedded systems.
💻 Affected Systems
- Qualcomm chipsets and devices using affected firmware
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, or persistent backdoor installation
Likely Case
Local privilege escalation or denial of service affecting device stability
If Mitigated
Contained privilege escalation or temporary service disruption with proper isolation
🎯 Exploit Status
Exploitation likely requires local access or ability to trigger specific partition operations
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check device manufacturer updates for specific firmware versions
Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/february-2026-bulletin.html
Restart Required: Yes
Instructions:
1. Check device manufacturer for security updates 2. Apply firmware update from OEM 3. Reboot device to complete installation
🔧 Temporary Workarounds
Restrict partition access
linuxLimit access to partition management functions to privileged users only
chmod 600 /dev/block/*
setenforce 1
🧯 If You Can't Patch
- Implement strict access controls to prevent unauthorized users from accessing partition operations
- Deploy runtime protection solutions that can detect memory corruption attempts
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against manufacturer's patched versions listCheck Version:
