Could you please push this patch into stable@? it fixes memory corruption in kernels v3.5 .. v4.10
Lost .data_len definition leads to write beyond end of struct nf_ct_h323_master. Usually it corrupts following struct nf_conn_nat, however if nat is not loaded it corrupts following slab object.
In mainline this problem went away in v4.11, after commit 9f0f3ebeda47 ("netfilter: helpers: remove data_len usage for inkernel helpers") however many stable kernels are still affected.
-stable maintainers of: 3.16, 4.4 and 4.9.
Now queued up to 4.4 and 4.9, thanks. 3.16 is end-of-life.
