CVE-2026-98296

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.
