CVE-2025-47380
📋 TL;DR
This vulnerability involves memory corruption in sensor IOCTL preprocessing, allowing attackers to potentially execute arbitrary code or cause system crashes. It affects systems using Qualcomm sensor drivers, primarily impacting mobile devices and IoT products with Qualcomm chipsets.
💻 Affected Systems
- Qualcomm sensor drivers
- Devices with Qualcomm chipsets
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with kernel-level code execution leading to complete device control and data exfiltration
Likely Case
Local privilege escalation allowing attackers to gain elevated permissions on compromised devices
If Mitigated
System crash or denial of service without code execution if exploit fails or protections are in place
🎯 Exploit Status
Requires local access or ability to execute code on device; IOCTL vulnerabilities typically require specific knowledge of driver internals
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Qualcomm security bulletin for specific chipset patches
Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/january-2026-bulletin.html
Restart Required: Yes
Instructions:
1. Check Qualcomm advisory for affected chipset versions
2. Obtain firmware/OS updates from device manufacturer
3. Apply patches following manufacturer instructions
4. Reboot device to activate fixes
🔧 Temporary Workarounds
Restrict sensor permissions
linuxLimit which applications can access sensor IOCTLs through SELinux/AppArmor policies
# Example SELinux policy to restrict sensor access
# Requires custom policy development for specific device
🧯 If You Can't Patch
- Isolate affected devices from critical networks
- Implement application allowlisting to prevent unauthorized code execution
🔍 How to Verify
Check if Vulnerable:
Check device chipset version and compare against Qualcomm advisory; examine kernel/driver versionsCheck Version:
# Android: getprop ro.boot.hardware
# Linux: cat /proc/cpuinfo | grep -i qualcommVerify Fix Applied:
Verify updated firmware version and check that sensor driver version matches patched release📡 Detection & Monitoring
