In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: configfs: Prevent OOB read/write in usb_string_copy()
Userspace provided string ‘s’ could trivially have the length zero. Left
unchecked this will firstly result in an OOB read in the form
if (str[0 - 1] == '\n') followed closely by an OOB write in the form str[0 - 1] = ‘\0’`.
There is already a validating check to catch strings that are too long.
Let’s supply an additional check for invalid strings that are too short.
