The Linux kernel's HID wacom driver had a flaw where wacom_parse_and_register() started the HID hardware before completing input registration and pad LED/remote initialization. If these later steps failed, the error paths released Wacom resources without stopping the HID hardware, potentially leaving hardware in an inconsistent state. The fix ensures that post-hid_hw_start() failures are routed through hid_hw_stop() before releasing driver resources, properly stopping the hardware. This vulnerability was discovered during static analysis research.

Improper handling of hardware stop procedures after initialization failures could lead to inconsistent hardware states or resource leaks within the kernel's HID wacom driver. No direct exploitation or active attacks are known. The impact is primarily on system stability and resource management rather than direct security compromise.

A fix has been implemented in the Linux kernel to properly stop the HID hardware after post-start probe failures in the wacom driver. Users should update to the fixed kernel version once available.
