An oversized packet_len\ncan lead to an out-of-bounds read in skb_put_data().\n\nValidate packet_len to ensure it is non-zero and does not exceed\nBTINTEL_PCIE_BUFFER_SIZE - sizeof(*rfh_hdr), logging an error when\ninvalid.\n\nThis issue was reported by Claude Mythos. It can be simulated either by\nusing customized firmware configured to return an invalid packet_len or\nby modifying rfh_hdr->packet_len in the driver before calling\nbtintel_pcie_submit_rx_work()."
