In the Linux kernel, the following vulnerability has been resolved: usb: core: config: Prevent OOB read in SS endpoint companion parsing usb_parse_ss_endpoint_companion() checks descriptor type before length, enabling a potentially odd read outside of the buffer size. Fix this up by checking the size first before looking at any of the fields in the descriptor.
