CVE-2025-24493
📋 TL;DR
This CVE describes a race condition vulnerability in OpenHarmony that allows local attackers to cause information leaks. The vulnerability affects OpenHarmony v5.0.3 and earlier versions, potentially exposing sensitive data to unauthorized local users.
💻 Affected Systems
- OpenHarmony
📦 What is this software?
Openharmony by Openatom
⚠️ Risk & Real-World Impact
Worst Case
Local attacker gains unauthorized access to sensitive system information, potentially including cryptographic keys, user data, or system configuration details.
Likely Case
Local user with limited privileges accesses information they shouldn't be able to see, potentially leading to privilege escalation or further system compromise.
If Mitigated
Information exposure limited to non-critical data with proper access controls and isolation mechanisms in place.
🎯 Exploit Status
Exploitation requires local access and timing the race condition correctly. No public exploit code has been identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after v5.0.3
Vendor Advisory: https://gitee.com/openharmony/security/blob/master/zh/security-disclosure/2025/2025-06.md
Restart Required: Yes
Instructions:
1. Check current OpenHarmony version. 2. Update to version newer than v5.0.3. 3. Reboot the system to apply changes.
🔧 Temporary Workarounds
Restrict local access
allLimit local user access to systems running vulnerable OpenHarmony versions
Implement strict access controls
allEnforce principle of least privilege for local users on affected systems
🧯 If You Can't Patch
- Isolate affected systems from sensitive networks and data
- Implement enhanced monitoring for unusual local access patterns
🔍 How to Verify
Check if Vulnerable:
Check OpenHarmony version with 'getprop ro.build.version.release' or similar system commandsCheck Version:
getprop ro.build.version.releaseVerify Fix Applied:
Verify version is newer than v5.0.3 and check that the update was successfully applied📡 Detection & Monitoring
Log Indicators:
- Unusual local process activity
- Multiple rapid access attempts to sensitive files
- Race condition timing patterns in system logs
Network Indicators:
- Not applicable - local vulnerability
SIEM Query:
Search for multiple rapid file access attempts from same local user within short timeframes
