Vulnerability Title
Bluetooth: btintel_pcie: fix TX descriptor bounds check
Source: CVE Program / CVE List V5
Vulnerability 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.
