  "details": "In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: btintel_pcie: validate device-supplied DMA indices  In btintel_pcie_msix_rx_handle(), the driver processes RX completion descriptors (urbd1) written by the PCIe device into DMA-coherent memory. urbd1-\u003efrbd_tag (a 16-bit field fully controlled by the device firmware via DMA) is used directly as an array index into rxq-\u003ebufs[] without any bounds check. rxq-\u003ebufs[] has only BTINTEL_PCIE_RX_DESCS_COUNT (64) entries, while frbd_tag can be any value 0-65535. A malicious or malfunctioning device can write an out-of-range frbd_tag, causing the driver to dereference an out-of-bounds data_buf pointer.  Additionally, cr_hia is read from a DMA-shared index array also writable by the device; if the device sets cr_hia \u003e= rxq-\u003ecount, the while-loop never terminates because cr_tia is wrapped via modulo rxq-\u003ecount and can never equal an out-of-range cr_hia.  Add bounds validation for cr_hia and frbd_tag in the RX path, and cr_hia in the TX path. Log invalid values with bt_dev_err before returning.",
