CVE-2026-43049

Kernel memory corruption via dangling HID objects

Published May 1, 2026 · Updated May 1, 2026

Use-after-free in the Linux Kernel HID++ driver allows local users to corrupt kernel memory after force-feedback setup fails. When Logitech G920 force-feedback initialization fails, probe returns an error without tearing down its sysfs and /dev/input objects. Local users must retain and access references to those dangling objects after the probe error, which can interrupt the host.
