    Added Description In the Linux kernel, the following vulnerability has been resolved:

    usb: gadget: configfs: Fix OOB read on empty string write

    When 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 beginning
    of os_desc_qw_sign_store() and webusb_landingPage_store() to handle
    the zero-length input case gracefully by returning immediately.
