Description

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

Bluetooth: hci_aml: validate firmware segment lengths

aml_download_firmware() reads two lengths from the firmware header and uses them to build pointers before checking that the header and segment data are present. A truncated or inconsistent firmware image can make the driver read past firmware->data while constructing TCI commands.

Reject images shorter than the header and ensure that the ICCM and DCCM ranges fit within the loaded firmware before downloading either segment.
