CVE-2026-1188
📋 TL;DR
CVE-2026-1188 is a buffer overflow vulnerability in Eclipse OMR's port library component where an API function fails to properly account for separator characters when writing processor feature names to a buffer. This allows attackers to potentially execute arbitrary code or crash applications. Affects any software using Eclipse OMR port library versions 0.2.0 through 0.7.x.
💻 Affected Systems
- Eclipse OMR port library component
📦 What is this software?
Omr by Eclipse
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, or service disruption.
Likely Case
Application crash causing denial of service, potentially leading to information disclosure via memory dumps.
If Mitigated
Limited impact with proper input validation and buffer size checking in calling code.
🎯 Exploit Status
Exploitation requires control over buffer size parameter and potentially the feature list. No public exploits known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.8.0
Vendor Advisory: https://github.com/eclipse-omr/omr/pull/8082
Restart Required: Yes
Instructions:
1. Update Eclipse OMR to version 0.8.0 or later. 2. Rebuild any applications using the OMR library. 3. Restart affected services.
🔧 Temporary Workarounds
Input validation wrapper
allImplement wrapper function that validates buffer size before calling vulnerable API
// C/C++ example: Ensure buffer size accounts for separators (n-1) between features
🧯 If You Can't Patch
- Disable or restrict access to functionality using the affected API
- Implement strict input validation and buffer size checking in application code
🔍 How to Verify
Check if Vulnerable:
Check Eclipse OMR version: if between 0.2.0 and 0.7.x inclusive, check if application uses port library processor feature API.Check Version:
Check build configuration or library version strings for 'omr' or 'Eclipse OMR'Verify Fix Applied:
Verify Eclipse OMR version is 0.8.0 or later and application has been rebuilt with updated library.📡 Detection & Monitoring
