DescriptionIn the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel_pcie: fix tx_handle bounds off-by-one 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'. This issue was reported by Claude Mythos.
