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

  - In the Linux kernel, the following vulnerability has been resolved: rxrpc: fix a race in rxrpc_exit_net()     Current code can lead to the following race: CPU0 CPU1 rxrpc_exit_net() rxrpc_peer_keepalive_worker() if     (rxnet->live) rxnet->live = false; del_timer_sync(&rxnet->peer_keepalive_timer);
    timer_reduce(&rxnet->peer_keepalive_timer, jiffies + delay);
    cancel_work_sync(&rxnet->peer_keepalive_work); rxrpc_exit_net() exits while peer_keepalive_timer is still     armed, leading to use-after-free. syzbot report was: ODEBUG: free active (active state 0) object type:
