CVE-2022-48866

Kernel memory disclosure via unchecked USB endpoints

Published Jul 16, 2024 · Updated May 11, 2026

Out-of-bounds read in Linux 5.13 through 5.15.28 and 5.16 through 5.16.14 allows local users to disclose kernel memory via a USB device. The hid-thrustmaster probe path indexes usb_host_interface::endpoint entries without first verifying that the interface exposes the expected endpoint count. Low-privileged local access and a malformed Thrustmaster-compatible USB interface are required; successful triggering can disclose kernel memory or crash the system.
