  • Patched TLS 1.3 session resumption vulnerability (CVE-2024-XXXXX)
  • Updated OpenSSL libraries to 3.0.18 with FIPS 140-3 compliance
  • Enhanced certificate revocation checking for AnyConnect VPN sessions

Platform Optimization

  • 20% faster policy deployment on Firepower 2140 clusters
  • Reduced memory consumption during large-scale NAT operations
  • Improved SSD health monitoring thresholds with predictive alerts

Protocol Support

  • Extended QUIC protocol inspection capabilities
  • Optimized HTTP/3 request smuggling detection algorithms
  • Added GTPv2-C message parsing for 5G core networks

Compatibility and Requirements

Supported Hardware

Model Series Minimum FXOS ASDM Version
Firepower 2110 2.6.1.105 7.16.2+
Firepower 2130 2.6.1.112 7.17.1+
