Dan Carpenter 5afc3791c8 net: nfc: fix bounds checking bugs on "pipe" ... [ Upstream commit a3aefbfe45751bf7b338c181b97608e276b5bb73 ] This is similar to commit 674d9de02a ("NFC: Fix possible memory corruption when handling SHDLC I-Frame commands") and commit d7ee81ad09 ("NFC: nci: Add some bounds checking in nci_hci_cmd_received()") which added range checks on "pipe". The "pipe" variable comes skb->data[0] in nfc_hci_msg_rx_work(). It's in the 0-255 range. We're using it as the array index into the hdev->pipes[] array which has NFC_HCI_MAX_PIPES (128) members.
