When the host wants to fetch OS descriptors, it sends two requests. The first is only for the header and the second for the full amount specified by the header in the first request. The OS descriptor handling code is distinguishing the header-only requests based on the wLength of the setup packet,

[PATCH 1/2] usb: gadget: composite: fix incorrect handling of OS desc requests

When handling an OS descriptor request, one of the first operations is to zero out the request buffer using the wLength from the setup packet. There is no bounds checking, so a wLength > 4096 would clobber memory adjacent to the request buffer. Fix this by taking the min of wLength and the request
