CVE-2026-43483: Nfsd Missing Fh Mac Check
NFS filehandles are predictable and lack cryptographic signatures. Decoding incoming filehandles without validating their authenticity allows an attacker to bypass path-based access controls by systematically guessing valid filehandles. Filehandles should be authenticated (e.g., via MAC check) before decoding.
