  "details": "In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: hci_core: Fix queuing tx_work after workqueue is drained  hci_send_acl(), hci_send_sco() and hci_send_iso() queue hdev-\u003etx_work unconditionally. They can run from the L2CAP/SCO/ISO socket send path while hci_dev_close_sync() is draining hdev-\u003eworkqueue (HCIDEVDOWN racing with a socket write). Since that queue_work() is not chained work from the tx_work worker itself, __queue_work() sees the queue marked __WQ_DRAINING, warns \"cannot queue %ps on wq %s\", and drops the work:    WARNING: CPU: 1 PID: 5985 at kernel/workqueue.c:2352 __queue_work   Call Trace:    queue_work_on    l2cap_chan_send    l2cap_sock_sendmsg    ...  hci_dev_close_sync() already sets HCI_CMD_DRAIN_WORKQUEUE before draining, but only hci_cmd_work() and handle_cmd_cnt_and_timer() check it before queuing. Route the tx_work producers through the same guard via a shared hci_sched_tx() helper.",
