Description

usb: gadget: configfs: Prevent OOB read/write in usb_string_copy()

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.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
