CVE-2024-22189
📋 TL;DR
This vulnerability allows attackers to cause memory exhaustion in quic-go implementations by sending excessive NEW_CONNECTION_ID frames while manipulating network conditions to prevent proper cleanup. It affects all systems using quic-go versions before 0.42.0 for QUIC protocol communication. The attack can lead to denial of service through resource exhaustion.
💻 Affected Systems
- quic-go
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete denial of service through memory exhaustion, potentially crashing the quic-go service and disrupting all QUIC connections.
Likely Case
Degraded performance and intermittent service disruptions as memory resources are consumed by connection ID management overhead.
If Mitigated
Minimal impact with proper monitoring and resource limits, though some performance degradation may still occur during attack attempts.
🎯 Exploit Status
Exploitation requires understanding of QUIC protocol mechanics and network manipulation, but detailed public documentation exists.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 0.42.0
Vendor Advisory: https://github.com/quic-go/quic-go/security/advisories/GHSA-c33x-xqrf-c478
Restart Required: Yes
Instructions:
1. Update quic-go dependency to version 0.42.0 or later. 2. Update go.mod to require github.com/quic-go/quic-go v0.42.0. 3. Run 'go mod tidy'. 4. Rebuild and redeploy application. 5. Restart all services using quic-go.
🧯 If You Can't Patch
- Implement network-level rate limiting for QUIC traffic to restrict connection ID frame frequency.
- Deploy memory monitoring and alerting for quic-go processes to detect memory exhaustion attempts early.
🔍 How to Verify
Check if Vulnerable:
Check go.mod or go.sum for quic-go version. If version is below 0.42.0, the system is vulnerable.Check Version:
grep 'quic-go' go.mod | grep -o 'v[0-9.]\+'Verify Fix Applied:
Verify quic-go version is 0.42.0 or higher in go.mod and that the application builds successfully with the updated dependency.📡 Detection & Monitoring
Log Indicators:
- Unusually high memory usage by quic-go processes
- Excessive connection ID retirement events
- Performance degradation in QUIC services
Network Indicators:
- High volume of NEW_CONNECTION_ID frames from single sources
- Abnormal QUIC packet patterns with selective acknowledgments
SIEM Query:
process:memory_usage > 90% AND process_name:quic-go OR protocol:QUIC AND frame_type:NEW_CONNECTION_ID COUNT > 1000 per source_ip🔗 References
