Mô tả CVE
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.
