Jeongjun Park 8619593634 wifi: ath9k: add range check for conn_rsp_epid in htc_connect_service()
I found the following bug in my fuzzer:

  UBSAN: array-index-out-of-bounds in drivers/net/wireless/ath/ath9k/htc_hst.c:26:51
  index 255 is out of range for type 'htc_endpoint [22]'
  CPU: 0 UID: 0 PID: 8 Comm: kworker/0:0 Not tainted 6.11.0-rc6-dirty #14
  Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014
  Workqueue: events request_firmware_work_func
  Call Trace:
   <TASK>
   dump_stack_lvl+0x180/0x1b0
   __ubsan_handle_out_of_bounds+0xd4/0x130
   htc_issue_send.constprop.0+0x20c/0x230
   ? _raw_spin_unlock_irqrestore+0x3c/0x70
   ath9k_wmi_cmd+0x41d/0x610
   ? mark_held_locks+0x9f/0xe0
   ...

Since this bug has been confirmed to be caused by insufficient verification
of conn_rsp_epid, I think it would be appropriate to add a range check for
conn_rsp_epid to htc_connect_service() to prevent the bug from occurring.

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 reStructuredText 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.
