CVE-2026-97976

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

Bluetooth: btintel_pcie: validate packet_len before skb_put_data

btintel_pcie_submit_rx_work() reads packet_len from rfh_hdr without

checking if it exceeds the RX buffer size. An oversized packet_len

can lead to an out-of-bounds read in skb_put_data().

Validate packet_len to ensure it is non-zero and does not exceed

BTINTEL_PCIE_BUFFER_SIZE - sizeof(*rfh_hdr), logging an error when

invalid.

This issue was reported by Claude Mythos. It can be simulated either by

using customized firmware configured to return an invalid packet_len or

by modifying rfh_hdr->packet_len in the driver before calling

btintel_pcie_submit_rx_work().
