A fix is available — apply it.

In the Linux kernel, the following vulnerability has been resolved:

HID: wacom: stop hardware after post-start probe failures

wacom_parse_and_register() starts HID hardware before registering inputs and initializing pad LEDs/remotes. Those later steps can fail, but their error paths currently release Wacom resources without stopping the HID hardware.

Route post-hid_hw_start() failures through hid_hw_stop() before releasing driver resources.

This issue was identified during our ongoing static-analysis research while reviewing kernel code.
