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.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
