Security Considerations

Crossing the user-kernel boundary represents a security risk if the kernel code operates on the data in any substantial way (beyond writing it to disk or passing it to another application). You must carefully perform bounds checking on any data passed in, and you must also make sure your code does not dereference memory that no longer belongs to the client application. Also, under no circumstances should you run unverified program code passed in from user space within the kernel. See “Security Considerations” for further information.
