AI-suggested
A fix has been committed that adds the missing hid_is_usb() check, resolving the issue. Users should apply the official Linux kernel update that includes this patch to mitigate the vulnerability. Patch status is not explicitly stated but the description confirms the issue is resolved by a commit.
Description
In the Linux kernel, the following vulnerability has been resolved: HID: asus: fix missing hid_is_usb() check to_usb_interface() can only be used on a hid_device whose parent is really USB; uhid can create devices that identify as being on BUS_USB, but don't actually have a USB parent. Fix the use of to_usb_interface() without a hid_is_usb() check. I have verified that it is currently possible to trigger a kernel splat due to this bug in an ASAN build, and that this commit fixes the issue.
