In the Linux kernel, the following vulnerability has been
resolved: inet: inet_defrag: prevent sk release while still in use
ip_local_out() and other functions can pass skb->sk as function argument.
If the skb is a fragment and reassembly happens before such function call
returns, the sk must not be released. This affects skb fragments
reassembled via netfilter or similar modules, e.g. openvswitch or ct_act.c,
when run as part of tx pipeline. Eric Dumazet made an initial analysis of
this bug. Quoting Eric: Calling ip_defrag() in output path is also implying
skb_orphan(), which is buggy because output path relies on sk not
disappearing. A rele
