## Overview

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btintel_pcie: validate TX skb length in send_sync

btintel_pcie_prepare_tx() copies skb->len bytes into a fixed
BTINTEL_PCIE_BUFFER_SIZE (4096) DMA slot via an unchecked memcpy.
Oversized packets are currently rejected only in
btintel_pcie_send_frame(); any future caller of
btintel_pcie_send_sync() would silently overflow the DMA buffer.

Add the bounds check in btintel_pcie_send_sync() itself, right
before skb_push() and the DMA copy.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
