CVE-2024-33061
📋 TL;DR
This vulnerability allows information disclosure through improper handling of IOCTL calls in Qualcomm trusted execution environments. Attackers can potentially read sensitive memory contents from trusted VM processes. This affects devices with Qualcomm chipsets that use vulnerable trusted execution implementations.
💻 Affected Systems
- Qualcomm chipsets with trusted execution environment features
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of trusted execution environment secrets, including cryptographic keys, authentication tokens, and sensitive application data stored in secure memory regions.
Likely Case
Limited information disclosure of memory contents from trusted applications, potentially exposing session data, configuration information, or partial cryptographic material.
If Mitigated
No impact if proper access controls prevent unauthorized users from making IOCTL calls to the vulnerable component.
🎯 Exploit Status
Exploitation requires ability to make IOCTL calls to the vulnerable component, typically requiring local code execution or elevated privileges.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to Qualcomm January 2025 security bulletin for specific patched versions
Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/january-2025-bulletin.html
Restart Required: Yes
Instructions:
1. Check Qualcomm January 2025 security bulletin for your specific chipset. 2. Obtain firmware/software updates from device manufacturer. 3. Apply updates following manufacturer instructions. 4. Reboot device to activate fixes.
🔧 Temporary Workarounds
Restrict IOCTL access
linuxLimit which processes can make IOCTL calls to trusted execution components
Device-specific SELinux/AppArmor policies required
Consult device manufacturer for specific configuration
🧯 If You Can't Patch
- Implement strict application sandboxing to prevent untrusted applications from accessing privileged interfaces
- Monitor for suspicious IOCTL calls to trusted execution environment components
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against Qualcomm security bulletin; examine if trusted execution environment is enabled and vulnerable versions are presentCheck Version:
Device-specific commands vary; typically 'getprop ro.build.version.security_patch' on Android or check /proc/version on Linux systemsVerify Fix Applied:
Verify firmware version has been updated to patched version listed in Qualcomm bulletin; test IOCTL handling in trusted execution environment📡 Detection & Monitoring
Log Indicators:
- Unusual IOCTL calls to trusted execution components
- Failed trusted execution environment operations
- Memory access violations in secure contexts
Network Indicators:
- Not network exploitable; focus on local system monitoring
SIEM Query:
