Description
An off-by-one bounds check vulnerability in the Linux kernel Bluetooth driver btintel_pcie was fixed. The function btintel_pcie_submit_rx() incorrectly allowed an index equal to the array count, leading to an out-of-bounds access. The check was corrected to reject all out-of-range indices.
