CVE-2025-47325
📋 TL;DR
This vulnerability allows attackers to access sensitive information by exploiting improper handling of system calls with invalid parameters. It affects systems using Qualcomm chipsets with vulnerable firmware. The information disclosure could reveal kernel memory contents or other protected data.
💻 Affected Systems
- Qualcomm chipsets and devices using vulnerable firmware
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could read kernel memory, potentially exposing encryption keys, passwords, or other sensitive system data leading to full system compromise.
Likely Case
Limited information disclosure revealing system state or configuration details that could aid further attacks.
If Mitigated
Minimal impact with proper access controls and network segmentation limiting exposure.
🎯 Exploit Status
Requires ability to make system calls with invalid parameters, typically through local access or compromised applications.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Firmware versions specified in December 2025 Qualcomm security bulletin
Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/december-2025-bulletin.html
Restart Required: Yes
Instructions:
1. Check Qualcomm advisory for affected chipset models. 2. Contact device manufacturer for firmware updates. 3. Apply firmware patches provided by device vendor. 4. Reboot device after update.
🔧 Temporary Workarounds
Restrict system call access
linuxImplement seccomp filters or similar mechanisms to restrict which system calls applications can make
Implement via application sandboxing or container security policies
Application sandboxing
linuxRun potentially untrusted applications in restricted environments with limited system call access
Use SELinux/AppArmor policies to restrict application capabilities
🧯 If You Can't Patch
- Implement strict network segmentation to isolate vulnerable devices
- Monitor for unusual system call patterns and privilege escalation attempts
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against Qualcomm advisory list of vulnerable versionsCheck Version:
cat /proc/version or check device firmware settingsVerify Fix Applied:
Verify firmware version matches or exceeds patched versions listed in Qualcomm bulletin📡 Detection & Monitoring
Log Indicators:
- Failed system calls with unusual parameters
- Kernel panic or warning messages related to system call handling
Network Indicators:
- Unusual local process communication patterns
SIEM Query:
Search for kernel logs containing 'invalid parameter' or 'system call error' from Qualcomm-related processes
