## Overview

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

net: usb: pegasus: 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. Instead of
keeping a side table for additional information, use driver_info field of
the usb_device_id.

The dynamic ID parsing code needs to be updated for this; convert it to
just write to the reserved entry for dynamic ID and remove the weird loop.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
