In the Linux kernel, the following vulnerability has been resolved:usb: gadget: configfs: Fix OOB read on empty string writeWhen writing an empty string to either 'qw_sign' or 'landingPage'sysfs attributes, the store functions attempt to access page[l - 1]before validating that the length 'l' is greater than zero.This patch fixes the vulnerability by adding a check at the beginningof os_desc_qw_sign_store() and webusb_landingPage_store() to handlethe zero-length input case gracefully by returning immediately.
