Overview

CVE-2026-98730 is a known-severity vulnerability. It was published on October 18, 2026.

Technical description

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

Bluetooth: btintel_pcie: reject oversized TX packets in send_frame()

btintel_pcie_send_frame() eventually copies skb->data into a fixed

BTINTEL_PCIE_BUFFER_SIZE (4096) DMA buffer via memcpy() in

btintel_pcie_prepare_tx(), with a 4-byte PCIe type header prepended.

A user-space process with HCI_CHANNEL_USER access can inject an

oversized packet and overflow the buffer.

Reject packets larger than

BTINTEL_PCIE_BUFFER_SIZE - BTINTEL_PCIE_HCI_TYPE_LEN on entry.
