Description

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.
