原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc2: Fix memory leak in dwc2_hcd_init
usb_create_hcd will alloc memory for hcd, and we should
call usb_put_hcd to free it when platform_get_resource()
fails to prevent memory leak.
goto error2 label instead error1 to fix this.
