Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: gadget: configfs: Fix OOB read on empty string write<br /> <br /> When writing an empty string to either &amp;#39;qw_sign&amp;#39; or &amp;#39;landingPage&amp;#39;<br /> sysfs attributes, the store functions attempt to access page[l - 1]<br /> before validating that the length &amp;#39;l&amp;#39; is greater than zero.<br /> <br /> This patch fixes the vulnerability by adding a check at the beginning<br /> of os_desc_qw_sign_store() and webusb_landingPage_store() to handle<br /> the zero-length input case gracefully by returning immediately.
