NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-container-debug package and not the kernel-uek-container-debug package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

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] == &#39;\n&#39;) 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.
