CVE-2026-46118: Nfsd Unauthenticated Filehandle Decode

NFS filehandles are decoded using an exportfs decode function without cryptographic verification. Because standard NFS filehandles are traditionally predictable, an unauthenticated network attacker can guess them to bypass path-based access controls and access restricted files. Ensure incoming filehandles are cryptographically verified (e.g., using `fh_verif
