CVE-2024-54030
📋 TL;DR
This CVE describes a use-after-free vulnerability in OpenHarmony v4.1.2 and earlier versions that allows a local attacker to cause a denial of service (DoS). The vulnerability affects systems running vulnerable versions of OpenHarmony, potentially disrupting service availability.
💻 Affected Systems
- OpenHarmony
📦 What is this software?
Openharmony by Openatom
⚠️ Risk & Real-World Impact
Worst Case
Complete system crash or kernel panic leading to sustained denial of service, requiring physical intervention to restore functionality.
Likely Case
Application or service crash causing temporary disruption until automatic or manual restart occurs.
If Mitigated
Limited impact with proper privilege separation and process isolation, potentially only affecting non-critical services.
🎯 Exploit Status
Exploitation requires local access and knowledge of the specific use-after-free condition. No public exploit code has been identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: OpenHarmony v4.1.3 or later
Vendor Advisory: https://gitee.com/openharmony/security/blob/master/zh/security-disclosure/2025/2025-01.md
Restart Required: Yes
Instructions:
1. Check current OpenHarmony version. 2. Update to OpenHarmony v4.1.3 or later using official update channels. 3. Reboot the system to apply the patch.
🔧 Temporary Workarounds
Restrict local user privileges
allLimit user privileges to reduce attack surface for local exploitation
Implement process isolation
allUse containerization or sandboxing to isolate vulnerable components
🧯 If You Can't Patch
- Implement strict access controls to limit local user access to vulnerable systems
- Deploy monitoring for abnormal process crashes or system instability
