Description
In the Linux kernel, the following vulnerability has been resolved:
usb: xusbatm: don't rely on id table pointer arithmetic
The current code is broken when dynamic ID is involved; in such cases
usb_device_id parameter of probe lives on the heap and the pointer
arithmetic will get an index that is wildly out of bound. xusbatm
initialize the USB device IDs dynamically so it can just use driver_info
too.
Even with conversion, xusbatm still cannot support dynamic IDs, so also set
no_dynamic_id.
