- Snapdragon Compute
- Snapdragon Connectivity
- Snapdragon Consumer IOT
- Snapdragon Mobile
- Snapdragon Wired Infrastructure and Networking
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with kernel-level code execution, allowing attackers to install persistent malware, steal sensitive data, or brick devices.
Likely Case
Local privilege escalation from user to kernel mode, enabling attackers to bypass security controls and gain elevated system access.
If Mitigated
Limited impact with proper kernel hardening, SELinux/AppArmor policies, and restricted user access preventing exploitation.
🎯 Exploit Status
Requires local access and kernel knowledge; no public exploit code available as per references.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Kernel patches available from Qualcomm in June 2020 security bulletin
Vendor Advisory: https://www.qualcomm.com/company/product-security/bulletins/june-2020-bulletin
Restart Required: Yes
Instructions:
1. Check device manufacturer for firmware updates. 2. Apply Qualcomm-provided kernel patches. 3. Rebuild kernel with security fixes. 4. Update device firmware. 5. Reboot system.
🔧 Temporary Workarounds
Restrict User Access
linuxLimit local user access to prevent exploitation attempts
# Use SELinux/AppArmor policies
# Restrict shell access
# Implement least privilege principles
Kernel Hardening
linuxEnable kernel security features to mitigate exploitation
# Enable KASLR: echo 2 > /proc/sys/kernel/randomize_va_space
# Enable kernel module signing
# Restrict debugfs access
🧯 If You Can't Patch
- Implement strict access controls and network segmentation
- Deploy endpoint detection and response (EDR) solutions
🔍 How to Verify
Check if Vulnerable:
Check kernel version and chipset: cat /proc/version && cat /proc/cpuinfo | grep -i qualcomm
Check Version:
uname -r && grep -i qualcomm /proc/cpuinfo
Verify Fix Applied:
Verify kernel version after update and check for June 2020 security patches
