"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfc: nci: fix circular locking dependency in nci_close_device\n\nnci_close_device() flushes rx_wq and tx_wq while holding req_lock.\nThis causes a circular locking dependency because nci_rx_work()\nrunning on rx_wq can end up taking req_lock too:\n\n nci_rx_work -> nci_rx_data_packet -> nci_data_exchange_complete\n -> __sk_destruct -> rawsock_destruct -> nfc_deactivate_target\n -> nci_deactivate_target -> nci_request -> mutex_lock(&ndev->req_lock)\n\nMove the flush of rx_wq after req_lock has been released.\nThis should safe (I think) because NCI_UP has already been cleared\nand the transport is closed, so the work will see it and return\n-ENETDOWN.\n\nNIPA has been hitting this running the nci selftest with a debug\nkernel on roughly 4% of the runs."
