Subject: Re: [PATCH net 2/3] inet_diag: validate byte code to prevent oops
 in inet_diag_bc_run()

> Previously we did not validate the inet_diag_hostcond, address family,
> address length, and prefix length. So a malicious user could make the
> kernel read beyond the end of the bytecode array by claiming to have a

> contain a whole inet_diag_hostcond of the given address family. Or

> a connection address by passing a prefix length that exceeded the
> length of addresses of the given family.
