CVE-2024-56629

System crash via null USB product name

Published Dec 27, 2024 · Updated May 11, 2026

NULL pointer dereference in the Linux kernel Wacom HID driver allows local users to crash the system by attaching a malformed USB device. In wacom_update_name, the driver replaced its fallback product_name with the nullable USB dev->product descriptor and later passed that null pointer to string handling. Triggering the fault requires attaching a device that exposes an empty product descriptor while the Wacom driver probes it; the reported consequence is a kernel crash.
