CVE-2026-3393
📋 TL;DR
A heap-based buffer overflow vulnerability exists in the SoLoud audio library's FLAC file parsing function. This allows local attackers to execute arbitrary code or crash applications using the library. Only applications that process FLAC files with the vulnerable SoLoud library are affected.

⚠️ Risk & Real-World Impact
Worst Case
Local privilege escalation leading to full system compromise if exploited by a malicious user with local access.
Likely Case
Application crash (denial of service) when processing specially crafted FLAC files.
If Mitigated
Limited impact if applications run with minimal privileges and don't process untrusted FLAC files.
🎯 Exploit Status
Exploit requires local access to supply malicious FLAC file. Public proof-of-concept available in GitHub repository.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://github.com/jarikomppa/soloud/issues/401
Restart Required: Yes
Instructions:
No official patch available. Vendor has not responded to vulnerability report. Consider alternative mitigations.
🔧 Temporary Workarounds
Disable FLAC file processing
allModify applications to avoid using SoLoud's FLAC parsing functionality
Modify source code to avoid SoLoud::Wav::loadflac calls
Input validation for FLAC files
allImplement strict validation of FLAC files before passing to SoLoud library
Implement file validation logic in application code
🧯 If You Can't Patch
- Restrict local user access to systems running vulnerable applications
- Run applications with minimal privileges and in sandboxed environments
🔍 How to Verify
Check if Vulnerable:
Check if application uses SoLoud library version 20200207 or earlier and processes FLAC filesCheck Version:
Check build configuration or dependency files for SoLoud versionVerify Fix Applied:
Verify application no longer uses vulnerable SoLoud version or has disabled FLAC processing📡 Detection & Monitoring
