  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\ncan: j1939: prevent deadlock by moving j1939_sk_errqueue()\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:\n3\nj1939_session_list_lock ->  active_session_list_lock\nj1939_session_activate\n...\nj1939_sk_queue_activate_next -> sk_session_queue_lock\n...\nj1939_xtp_rx_eoma_one\n2\nj1939_sk_queue_drop_all  ->  sk_session_queue_lock\n...\nj1939_sk_netdev_event_netdown -> j1939_socks_lock\nj1939_netdev_notify\n1\nj1939_sk_errqueue -> j1939_socks_lock\n__j1939_session_cancel -> active_session_list_lock\nj1939_tp_rxtimer\nCPU0                    CPU1\n----                    ----\nlock(&priv->active_session_list_lock);\nlock(&jsk->sk_session_queue_lock);\nlock(&priv->active_session_list_lock);\nlock(&priv->j1939_socks_lock);\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.", "A flaw was found in the Linux kernel. A local user with low privileges could exploit a deadlock vulnerability in the Controller Area Network (CAN) bus J1939 protocol implementation. This occurs when specific data transfer and error queue handling events coincide with a network interface going down. Successful exploitation can lead to a Denial of Service (DoS), rendering the system unresponsive." ],
