Description
In the Linux kernel, the following vulnerability has been resolved: netrom: Fix memory leak in nr_sendmsg() syzbot reported a memory leak [1]. When function sock_alloc_send_skb() return NULL in nr_output(), the original skb is not freed, which was allocated in nr_sendmsg(). Fix this by freeing it before return.
