CVE-2022-46701

Kernel code execution via malformed NFS responses

Published Dec 15, 2022 · Updated Apr 18, 2025

Kernel code execution in Apple tvOS before 16.2 allows local users to gain kernel privileges by connecting to a malicious NFS server. The kernel NFS client applies inadequate bounds checks while processing server-supplied NFS data, but Apple has not disclosed the affected function or field. Exploitation requires local low-privileged access and control of an NFS server selected by the target; successful exploitation executes code with kernel privileges.
