CVE-2024-58107
📋 TL;DR
A buffer overflow vulnerability in the codec module could allow attackers to crash affected systems, potentially causing denial of service. This affects Huawei devices and software using the vulnerable codec component. Systems processing untrusted media files are particularly at risk.
💻 Affected Systems
- Huawei devices with vulnerable codec module
📦 What is this software?
Harmonyos by Huawei
⚠️ Risk & Real-World Impact
Worst Case
Complete system crash or reboot, potentially leading to extended service disruption and requiring manual intervention to restore functionality.
Likely Case
Application or service crash when processing malicious media files, causing temporary service interruption until automatic restart mechanisms activate.
If Mitigated
Controlled crash of only the affected codec process with minimal service impact if proper isolation and monitoring are implemented.
🎯 Exploit Status
Exploitation requires crafting a malicious media file that triggers the buffer overflow when processed by the vulnerable codec.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Huawei security bulletin for specific patched versions
Vendor Advisory: https://consumer.huawei.com/en/support/bulletin/2025/4/
Restart Required: Yes
Instructions:
1. Check Huawei security advisory for affected products. 2. Apply the latest security update from Huawei. 3. Reboot the device after update installation. 4. Verify the patch is applied successfully.
🔧 Temporary Workarounds
Disable vulnerable codec processing
allRestrict or disable processing of media files from untrusted sources to prevent exploitation
# Configuration varies by device; check Huawei documentation for specific media processing controls
Implement input validation
allAdd file validation and sanitization for media uploads to reject potentially malicious files
# Implement file type validation and size limits in applications accepting media uploads
🧯 If You Can't Patch
- Isolate affected systems in network segments with restricted access
- Implement strict monitoring for media processing failures and system crashes
🔍 How to Verify
Check if Vulnerable:
Check device firmware version against Huawei's affected version list in their security advisoryCheck Version:
# On Huawei devices: Settings > System & updates > Software update > Current versionVerify Fix Applied:
Verify the installed firmware version matches or exceeds the patched version specified by Huawei📡 Detection & Monitoring
Log Indicators:
- Unexpected codec process crashes
- Media processing failures with abnormal exit codes
- System logs showing buffer overflow errors
Network Indicators:
- Unusual media file upload patterns
- Multiple failed media processing attempts from single source
