CVE-2025-21472
📋 TL;DR
This vulnerability allows unauthorized access to sensitive information when logs are captured, as eSE debug messages containing potentially sensitive data are logged. It affects systems using Qualcomm chipsets with eSE functionality. The risk primarily impacts devices where debug logging is enabled.
💻 Affected Systems
- Qualcomm chipsets with eSE (embedded Secure Element) functionality
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could extract cryptographic keys, authentication tokens, or other sensitive data from debug logs, potentially leading to complete system compromise.
Likely Case
Limited information disclosure of non-critical debug data, possibly revealing system state or configuration details.
If Mitigated
Minimal impact if debug logging is disabled or logs are properly secured with restricted access.
🎯 Exploit Status
Requires ability to access or capture system logs where debug messages are stored.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to Qualcomm August 2025 security bulletin for specific patched versions
Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/august-2025-bulletin.html
Restart Required: No
Instructions:
1. Check Qualcomm August 2025 security bulletin for affected chipsets. 2. Apply firmware/software updates from device manufacturer. 3. Verify debug logging settings are properly configured post-update.
🔧 Temporary Workarounds
Disable eSE debug logging
AndroidPrevents sensitive information from being written to logs by disabling debug logging for eSE components.
adb shell setprop persist.vendor.qsee.logs.enable 0
adb shell reboot
🧯 If You Can't Patch
- Disable all unnecessary debug logging system-wide
- Implement strict access controls on log files and directories
🔍 How to Verify
Check if Vulnerable:
Check if eSE debug logging is enabled: adb shell getprop persist.vendor.qsee.logs.enableCheck Version:
adb shell getprop ro.build.version.security_patchVerify Fix Applied:
Verify debug logging is disabled and check system logs for eSE debug messages📡 Detection & Monitoring
Log Indicators:
- eSE debug messages in system logs
- Unexpected access to log files containing debug information
Network Indicators:
- Unusual log file transfers or exfiltration
