CVE-2025-47372
📋 TL;DR
This vulnerability allows attackers to execute arbitrary code or cause denial of service by providing a specially crafted ELF file with an oversized file size, leading to memory corruption. It affects systems that process untrusted ELF images without proper validation. Primarily impacts Qualcomm-based devices and software that handle ELF file parsing.
💻 Affected Systems
- Qualcomm chipsets and associated software
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with kernel privileges leading to complete system compromise
Likely Case
Denial of service through system crashes or privilege escalation
If Mitigated
Contained impact with proper input validation and memory protections
🎯 Exploit Status
Requires delivering a malicious ELF file; exploitation depends on memory layout and mitigations
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Qualcomm December 2025 security bulletin for specific versions
Vendor Advisory: https://docs.qualcomm.com/product/publicresources/securitybulletin/december-2025-bulletin.html
Restart Required: Yes
Instructions:
1. Review Qualcomm December 2025 security bulletin. 2. Apply firmware/software updates from device manufacturer. 3. Reboot affected systems.
🔧 Temporary Workarounds
Restrict ELF file processing
allLimit processing of ELF files from untrusted sources
Enable memory protections
linuxUse ASLR, DEP, and other memory corruption mitigations
🧯 If You Can't Patch
- Isolate systems processing ELF files from untrusted networks
- Implement strict file validation and size checking for ELF inputs
🔍 How to Verify
Check if Vulnerable:
Check system firmware/software version against Qualcomm advisoryCheck Version:
Device-specific; typically 'cat /proc/version' or manufacturer toolsVerify Fix Applied:
Confirm updated version matches patched versions in Qualcomm bulletin📡 Detection & Monitoring
Log Indicators:
