+Subject: Bluetooth: MGMT: Add error handling to pair_device()
+
+From: Griffin Kroah-Hartman <griffin@kroah.com>
+
+commit 538fd3921afac97158d4177139a0ad39f056dbb2 upstream.
+
+hci_conn_params_add() never checks for a NULL value and could lead to a NULL
+pointer dereference causing a crash.
+
+Fixed by adding error handling in the function.
+
+Cc: Stable <stable@kernel.org>
+Fixes: 5157b8a503fa ("Bluetooth: Fix initializing conn_params in scan phase")
