CVE-2025-38497
What it is
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.
