CVE-2025-38654

Unspecified impact via premature pinctrl registration

Published Aug 22, 2025 · Updated May 11, 2026

Use of uninitialized resources in Linux 6.13 through 6.16 allows attackers to cause unspecified impact via unspecified vectors. The k230_pinctrl_probe function registers the controller before k230_pinctrl_parse_dt initializes the pin resources consumed during registration. Exposure requires the Canaan K230 pinctrl driver to probe a device-tree-backed platform; no concrete security consequence has been published.
