CVE-2026-80769Hinoki check available

Kernel splat via unchecked HID parent conversion

Published Sep 4, 2026 · Updated Sep 4, 2026

Invalid parent conversion in the Linux kernel Rapoo HID driver in 7.0 allows local users to trigger a kernel splat via a uhid device. The rapoo_probe path calls to_usb_interface on a parent selected from BUS_USB metadata without confirming that the parent is a USB interface. Reachability requires creation of a uhid device that claims BUS_USB without a USB parent; the demonstrated consequence is a kernel splat in an ASAN build.
