CVE-2024-45578
📋 TL;DR
This vulnerability allows memory corruption during IOCTL operations in Qualcomm IFE (Image Front End) drivers when validating output resource IDs. Attackers could potentially execute arbitrary code or cause denial of service. This affects devices using Qualcomm chipsets with vulnerable IFE drivers.
💻 Affected Systems
- Qualcomm chipsets with IFE (Image Front End) hardware
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Local privilege escalation to kernel mode, allowing complete system compromise and persistent access.
Likely Case
Local denial of service (system crash/reboot) or limited information disclosure from kernel memory.
If Mitigated
Limited impact if proper access controls restrict direct hardware access to privileged users only.
🎯 Exploit Status
Requires local access and ability to interact with IFE driver IOCTLs; kernel exploitation knowledge needed for full privilege escalation
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Refer to Qualcomm security bulletin for chipset-specific patched versions
Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/may-2025-bulletin.html
Restart Required: Yes
Instructions:
1. Check Qualcomm advisory for your specific chipset. 2. Obtain updated firmware/drivers from device manufacturer. 3. Apply updates following manufacturer instructions. 4. Reboot device to load patched drivers.
🔧 Temporary Workarounds
Restrict IFE driver access
linuxLimit access to IFE driver device nodes to prevent unauthorized IOCTL calls
chmod 600 /dev/ife*
set appropriate SELinux/AppArmor policies for IFE devices
🧯 If You Can't Patch
- Implement strict application sandboxing to prevent untrusted apps from accessing hardware interfaces
- Monitor for unusual IFE driver activity or unexpected system crashes
🔍 How to Verify
Check if Vulnerable:
Check Qualcomm chipset version and compare against patched versions in security bulletinCheck Version:
cat /proc/cpuinfo | grep -i qualcomm && dmesg | grep -i ifeVerify Fix Applied:
Verify driver version matches patched version from Qualcomm advisory; test IFE functionality remains operational📡 Detection & Monitoring
Log Indicators:
- Kernel panic logs
- IFE driver error messages in dmesg
- Unexpected IOCTL calls to IFE devices
Network Indicators:
- Not network exploitable
