- Eliminates buffer overflow in IoT MAC randomization (CVE-2025-32801)
- Fixes certificate validation bypass in quantum-key handshake (CVE-2025-32802)
- Addresses 3 high-risk OpenSSL 3.3.2 vulnerabilities
2. Cryptographic Enhancements
- CRYSTALS-Kyber (ML-KEM-768) trial implementation
- Hybrid key exchange support (X25519 + Kyber768)
- FIPS 140-3 Level 4 transitional compliance
3. Operational Stability
- Reduces TLS 1.3 session establishment latency by 25%
- Improves cluster config synchronization success rate to 99.99%
- Enhanced core dumps for forensic analysis
Compatibility and Requirements
| Component | Minimum Requirement | Maximum Supported |
|---|---|---|
| Hardware | SSP 7120 | SSP 7160 |
| FTD Version | 7.1.0.1 | 7.1.0.6 |
