CVE-2026-98730 in Linux
الملخص
بحسب MITRE • 18/10/2026
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.
