Unfortunately this just confirms that your skb has been freed
prematurely because 6b is the poison value.

However, it doesn't point us at the offender.

Although I wonder if there might be something in netfilter that's
freeing it since that's the only thing that could've run on your
machine between the previous access and the crash.  I'll take
another look.

Cheers,
