CVE-2026-80769
N/A
Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: rapoo: 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.
Add a dependency on USB_HID for hid_is_usb(), as other HID drivers do; the alternative would be to provide a simple stub implementation on !USB_HID builds.
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.
