FortiOS and CVE-2026-31431

Hey folks. I believe FortiOS runs some modified form of the Linux kernel. I'm not sure if that's true though. (Is it?) If you haven't heard, CVE-2026-31431 was announced today and many of us are scrambling to patch Linux servers.

If FortiOS is running a Linux kernel, I am wondering if this CVE will be an issue for us? Particularly if we're running FortiOS on a VM. Thoughts?
