CVE-2024-45547
📋 TL;DR
This vulnerability allows memory corruption through a specific IOCTL call when processing FIPS encryption/decryption verification in Qualcomm components. Attackers could potentially execute arbitrary code or cause system crashes. Affects devices with Qualcomm chipsets that implement the vulnerable FIPS functionality.
💻 Affected Systems
- Qualcomm chipsets with FIPS encryption/decryption functionality
📦 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
Local privilege escalation allowing attackers to gain elevated privileges on affected devices.
If Mitigated
System crash or denial of service if memory corruption cannot be leveraged for code execution.
🎯 Exploit Status
Requires local access and knowledge of the specific IOCTL interface; memory corruption exploitation requires additional techniques
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Qualcomm January 2025 security bulletin for specific patched versions
Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/january-2025-bulletin.html
Restart Required: No
Instructions:
1. Check Qualcomm advisory for affected chipset versions. 2. Obtain firmware/software updates from device manufacturer. 3. Apply patches according to manufacturer instructions. 4. Verify patch installation.
🔧 Temporary Workarounds
Restrict IOCTL access
Linux-based systemsLimit user-space access to the vulnerable IOCTL interface through SELinux/AppArmor policies or kernel module restrictions
# Example: Add SELinux policy to restrict ioctl access
# consult your specific OS documentation for exact commands
🧯 If You Can't Patch
- Implement strict access controls to prevent untrusted users from accessing the vulnerable interface
- Monitor for abnormal IOCTL calls and system crashes related to FIPS functionality
🔍 How to Verify
Check if Vulnerable:
Check Qualcomm chipset version and compare against advisory; examine system logs for FIPS-related IOCTL callsCheck Version:
# Check Qualcomm chipset version: cat /proc/cpuinfo | grep -i qualcommVerify Fix Applied:
Verify patch version from Qualcomm bulletin is installed; test FIPS functionality after patching📡 Detection & Monitoring
Log Indicators:
- Kernel panic logs
- IOCTL access violations
- FIPS module crash reports
Network Indicators:
- Not network exploitable; focus on local system monitoring
