CVE-2026-46269

Local kernel crash via uninitialized pinctrl pointer

Published Jun 3, 2026 · Updated Jun 3, 2026

NULL pointer dereference in the Linux Kernel K230 pinctrl driver allows local users to crash the kernel during device-tree probing. k230_pinctrl_parse_functions() dereferences info->pctl_dev->dev while parsing the device tree, before k230_pinctrl_probe() initializes info->pctl_dev. Reaching the fault requires an affected kernel to probe the Canaan K230 pinctrl device-tree node; the bounded consequence is a system crash.
