  • ​​FG-IR-25-063​​: Addressed privilege escalation via crafted DHCPv6 packets
  • Updated FortiGuard IPS signatures to detect 8 new ransomware command patterns

​​2. Hardware Optimization​​

  • Reduced NP6 processor memory consumption by 32% during concurrent PoE device management
  • Enhanced SSD endurance through adaptive wear-leveling for RAID 1 configurations

​​3. Protocol Stack Updates​​

  • Implemented RFC 9114 compliance for HTTP/3 traffic inspection
  • Added ED25519 signature support for SSHv2 management sessions

​​4. Operational Enhancements​​
