Summary
In the Linux kernel, the following vulnerability has been resolved: af_unix: fix use-after-free in unix_stream_read_actor() syzbot reported the following crash [1] After releasing unix socket lock, u->oob_skb can be changed by another thread. We must temporarily increase skb refcount to make sure this other thread will not free the skb under us.
