Introduction to FGT_VM64_KVM-v7.4.1.F-build2463-FORTINET.out

The FGT_VM64_KVM-v7.4.1.F-build2463-FORTINET.out firmware package delivers essential security patches and operational enhancements for Fortinet’s virtualized next-generation firewall solutions. Designed for KVM (Kernel-based Virtual Machine) hypervisors, this Q2 2025 release addresses critical vulnerabilities in SSL/TLS inspection modules while introducing hardware-assisted cryptographic acceleration for cloud environments.

This build specifically supports FortiGate-VM64 instances deployed on Red Hat Enterprise Linux 8.6+ and CentOS Stream 9 platforms, aligning with FortiOS 7.4.1’s expanded threat protection capabilities. The build2463 revision resolves 12 high-severity CVEs disclosed in Fortinet’s April 2025 security advisory, including memory corruption flaws in IPsec VPN implementations.
