There is a missing check between kmsg->msg_controllen and cmlen,
which can possibly lead to overflow.
This bug is similar to vulnerability that was fixed in commit 6900317f5eff
("net, scm: fix PaX detected msg_controllen overflow in scm_detach_fds").

If vpif_probe() fails on v4l2_device_register() and vpif_probe_complete(),
then memory allocated at initialize_vpif() for global vpif_obj.dev[i]
become unreleased.
The patch adds deallocation of vpif_obj.dev[i] on the error path.

Yes, you are correct. I will fix the issue and resubmit the patch again.

the same time, there are bugs in mip6_destopt_offset() and
mip6_destopt_offset(), which is similar to CVE-2017-7542.

Based on your explanation, I found that the patch I submitted is useless.

Clearing the IFF_ALLMULTI flag on a down interface could cause an allmulti
overflow on the underlying interface.
Attempting the set IFF_ALLMULTI on the underlying interface would cause an
error and the log message:
"allmulti touches root, set allmulti failed."

I am not so sure about taking off the cast, just to be in line with
patch in 194b3da873fd.
The comment can be deleted.
