The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - tcp_bpf: Call sk_msg_free() when tcp_bpf_send_verdict() fails to allocate psock->cork. syzbot reported the     splat below. [0] The repro does the following: 1. Load a sk_msg prog that calls bpf_msg_cork_bytes(msg,     cork_bytes) 2. Attach the prog to a SOCKMAP 3. Add a socket to the SOCKMAP 4. Activate fault injection 5.
    Send data less than cork_bytes At 5., the data is carried over to the next sendmsg() as it is smaller than     the cork_bytes specified by bpf_msg_cork_bytes(). Then, tcp_bpf_send_verdict() tries to allocate     psock->cork to hold the data, but this fails silently due to fault injection + __GFP_NOWARN. If the     allocation fails, we need to revert the sk->sk_forward_alloc change done by sk_msg_alloc(). Let's call     sk_msg_free() when tcp_bpf_send_verdict fails to allocate psock->cork. The *copied also needs to be     updated such that a proper error can be returned to the caller, sendmsg. It fails to allocate psock->cork.
    Nothing has been corked so far, so this patch simply sets *copied to 0. [0]: WARNING:
