Subject: [PATCH v1 2/2] Bluetooth: btintel_pcie: fix tx_handle bounds off-by-one
Date: Wed, 2 Sep 2026 18:48:30 +0530 [thread overview]
Message-ID: <20260902131830.35502-2-kiran.k@intel.com> (raw)
In-Reply-To: <20260902131830.35502-1-kiran.k@intel.com>
Valid indices into txq->urbd0s/tfds/bufs are 0..txq->count-1, so
tfd_index == txq->count is already out of range. Change the guard in
btintel_pcie_msix_tx_handle() from '> txq->count' to '>= txq->count'.
Fixes: c2b636b3f788 ("Bluetooth: btintel_pcie: Add support for PCIe transport")
