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.

Fixes: 118278f20a ("NFC: hci: Add pipes table to reference them with a tuple {gate, host}")

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
