## Overview

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btintel_pcie: fix TX descriptor bounds check

btintel_pcie_prepare_tx() uses tfd_index to access the TFD and data
buffer arrays before the index is advanced modulo txq->count. An index
equal to txq->count is one past the end of both arrays, so reject it in
the bounds check.

## Affected

- `Linux >= 6e65a09f927566f257322358d429b267548473eb < 08704ec6d4bf69725e7815b09a9b5c7af83e255b`

- `Linux >= 6e65a09f927566f257322358d429b267548473eb < 2669567615215d52fb306053cbcc1f53dc386158`
- `Linux >= 6e65a09f927566f257322358d429b267548473eb < baa53af641c9e3644e717b8dfd1b95a55a0c111b`
