Description OSIDB Bzimport 2026-09-04 15:38:09 UTC
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.
