In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_queue: fix possible use-after-free
Eric Dumazet says: The sock_hold() side seems suspect, because there is no guarantee that sk_refcnt is not already 0.
On failure, we cannot queue the packet and need to indicate an error. The packet will be dropped by the caller.
