      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ncan: j1939: prevent deadlock by moving j1939_sk_errqueue()\n\nThis commit addresses a deadlock situation that can occur in certain\nscenarios, such as when running data TP/ETP transfer and subscribing to\nthe error queue while receiving a net down event. The deadlock involves\nlocks in the following order:\n\n3\n  j1939_session_list_lock ->  active_session_list_lock\n  j1939_session_activate\n  ...\n  j1939_sk_queue_activate_next -> sk_session_queue_lock\n  ...\n  j1939_xtp_rx_eoma_one\n\n2\n  j1939_sk_queue_drop_all  ->  sk_session_queue_lock\n  ...\n  j1939_sk_netdev_event_netdown -> j1939_socks_lock\n  j1939_netdev_notify\n\n1\n  j1939_sk_errqueue -> j1939_socks_lock\n  __j1939_session_cancel -> active_session_list_lock\n  j1939_tp_rxtimer\n\n       CPU0                    CPU1\n       ----                    ----\n  lock(&priv->active_session_list_lock);\n                               lock(&jsk->sk_session_queue_lock);\n                               lock(&priv->active_session_list_lock);\n  lock(&priv->j1939_socks_lock);\n\nThe solution implemented in this commit is to move the\nj1939_sk_errqueue() call out of the active_session_list_lock context,\nthus preventing the deadlock situation.",
