In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: core: Check for unset descriptor
Make sure the descriptor has been set before looking at maxpacket.
This fixes a null pointer panic in this case.
This may happen if the gadget doesn’t properly set up the endpoint
for the current speed, or the gadget descriptors are malformed and
the descriptor for the speed/endpoint are not found.
No current gadget driver is known to have this problem, but this
may cause a hard-to-find bug during development of new gadgets.
