  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: mgmt: fix UAF in pair command cancellation\n\nThe pairing completion and authentication failure callbacks look up the\npending MGMT_OP_PAIR_DEVICE command by walking hdev-\u003emgmt_pending. The\nlookup returned a command that was still linked on the shared pending list,\nwithout keeping mgmt_pending_lock held for the later dereference and\nremoval.\n\nA concurrent MGMT_OP_CANCEL_PAIR_DEVICE request can remove and free the\nsame pending command before the callback uses it. The reverse race is also\npossible when cancel_pair_device() gets a command from pending_find() and a\ncallback removes it before the cancel path dereferences it. This can lead\nto a use-after-free and a second list_del().\n\nMake the pairing lookup helpers transfer ownership of the pending command\nby removing it from hdev-\u003emgmt_pending while holding mgmt_pending_lock.\nThe callbacks and cancel path then complete the command and free it\ndirectly, so racing paths cannot find or free the same command again. Take\na temporary hci_conn reference in cancel_pair_device() because the command\ncompletion drops the reference stored in the pending command.",
