Summary
In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: function: rndis: add length check to response query
Add variable representations for BufLength and BufOffset in rndis_query_response(), and perform a length check on them.
This is identical to how rndis_set_response() handles these parameters.
