FKIE_CVE-2026-68091
Vulnerability from fkie_nvd - Published: 2026-08-10 12:17 - Updated: 2026-08-17 05:18
Severity
Summary
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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
