Bluetooth: btintel_pcie: fix off-by-one bounds check in RX submit PUBLISHED

Description (CNA)

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel_pcie: fix off-by-one bounds check in RX submit btintel_pcie_submit_rx() used frbd_index > rxq->count to guard the FRBD array access, allowing frbd_index == rxq->count to pass through and index one element past the end of the array. Change the check to >= rxq->count so every out-of-range index is rejected. This issue was reported by Claude Mythos.
