CVE-2026-80774Hinoki check available

Kernel splat via unverified USB parent cast

Published Sep 4, 2026 · Updated Sep 4, 2026

Improper device validation in affected Linux kernels allows local users to trigger a kernel splat through a crafted uhid device. The ASUS HID probe path calls to_usb_interface() from the BUS_USB label without verifying that the hid_device parent is a USB interface. The trigger requires local access to /dev/uhid to create a device labeled BUS_USB without a USB parent; published evidence demonstrates a diagnostic fault in an ASAN build, not a system crash.
