CVE-2025-47349
📋 TL;DR
This CVE describes a memory corruption vulnerability in Qualcomm components that occurs while processing escape calls. Attackers could exploit this to execute arbitrary code or cause denial of service. The vulnerability affects devices using Qualcomm chipsets, particularly mobile devices and IoT products.
💻 Affected Systems
- Qualcomm chipsets and associated 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
Application crashes, denial of service, or limited information disclosure due to memory corruption.
If Mitigated
Controlled crashes without code execution if memory protections are enabled.
🎯 Exploit Status
Exploitation requires specific conditions to trigger the escape call processing; no public exploits known at this time
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Qualcomm's October 2025 security bulletin for specific firmware versions
Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/october-2025-bulletin.html
Restart Required: Yes
Instructions:
1. Check Qualcomm advisory for affected chipset models. 2. Contact device manufacturer for firmware updates. 3. Apply firmware patches provided by OEM. 4. Reboot device after update.
🔧 Temporary Workarounds
Disable unnecessary escape call features
allIf possible, disable or restrict escape call functionality in affected components
Configuration varies by device; consult manufacturer documentation
🧯 If You Can't Patch
- Isolate affected devices from untrusted networks
- Implement strict access controls and monitoring for suspicious memory-related activities
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against Qualcomm's advisory; use 'getprop ro.bootloader' on Android devices to check bootloader versionCheck Version:
Android: 'getprop ro.bootloader' or 'getprop ro.build.fingerprint'; Linux: check /proc/device-tree/modelVerify Fix Applied:
Verify firmware version has been updated to patched version listed in Qualcomm bulletin📡 Detection & Monitoring
Log Indicators:
