the Linux kernel, the following vulnerability has been resolved:  Bluetooth: hci_sync: Fix UAF in le_read_features_complete  This fixes the following backtrace caused by hci_conn being freed before le_read_features_complete but after hci_le_read_remote_features_sync so hci_conn_del -> hci_cmd_sync_dequeue is not able to prevent it:
