CVE-2026-64301

Resource leak via unreleased device-node reference

Published Jul 25, 2026 · Updated Jul 25, 2026

Resource leak in the Linux Kernel SCMI regulator driver allows attackers to retain a device-node reference via unspecified vectors. On the process_scmi_regulator_of_node() error path, scmi_regulator_probe() returns after of_find_node_by_name() without calling of_node_put() on the child node. The public record identifies neither an attacker-controlled trigger nor a resulting crash, hang, or other service impact.
