Summary
usb: gadget : fix use-after-free in composite_dev_cleanup()
Details

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

usb: gadget : fix use-after-free in composite_dev_cleanup()

  1. In func configfs_composite_bind() -> composite_os_desc_req_prepare(): if kmalloc fails, the pointer cdev->os_desc_req will be freed but not set to NULL. Then it will return a failure to the upper-level function.
  2. in func configfs_composite_bind() -> composite_dev_cleanup(): it will checks whether cdev->os_desc_req is NULL. If it is not NULL, it will attempt to use it.This will lead to a use-after-free issue.
