Description

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.
