CVE-2025-14310
📋 TL;DR
A classic buffer overflow vulnerability in RethinkDB allows attackers to write data beyond allocated memory boundaries by providing oversized input. This affects all RethinkDB installations running versions before 2.4.4. Attackers could potentially execute arbitrary code or crash the database service.
💻 Affected Systems
- RethinkDB
⚠️ 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
Remote code execution leading to complete system compromise, data theft, or ransomware deployment
Likely Case
Service crash causing denial of service and potential data corruption
If Mitigated
Limited impact if proper network segmentation and least privilege controls are implemented
🎯 Exploit Status
Buffer overflow vulnerabilities typically require some technical expertise to exploit, but public details in the pull request could lower the barrier
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.4.4
Vendor Advisory: https://github.com/rethinkdb/rethinkdb/pull/7163
Restart Required: Yes

1. Backup your RethinkDB data. 2. Stop the RethinkDB service. 3. Upgrade to version 2.4.4 or later. 4. Restart the RethinkDB service. 5. Verify the upgrade was successful.
🔧 Temporary Workarounds
Network Segmentation
linuxRestrict network access to RethinkDB to only trusted systems
iptables -A INPUT -p tcp --dport 28015 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 28015 -j DROP
Service Restriction
linuxRun RethinkDB with minimal privileges and in isolated environments
sudo -u rethinkdb rethinkdb --daemon
🧯 If You Can't Patch
- Implement strict network access controls to limit who can connect to RethinkDB
- Deploy intrusion detection systems to monitor for buffer overflow attempts
🔍 How to Verify
Check if Vulnerable:
Check RethinkDB version. If version is less than 2.4.4, the system is vulnerableCheck Version:
rethinkdb --versionVerify Fix Applied:
Confirm RethinkDB version is 2.4.4 or higher and test database functionality📡 Detection & Monitoring
Log Indicators:
- Segmentation fault errors
- Unexpected process termination
- Memory allocation failures
Network Indicators:
- Unusually large network packets to RethinkDB port 28015
- Multiple connection attempts with malformed data
SIEM Query:
source="rethinkdb.log" AND ("segmentation fault" OR "buffer overflow" OR "SIGSEGV")
