CVE-2026-64301
Published Jul 25, 2026
Description
In the Linux kernel, the following vulnerability has been resolved: regulator: scmi: fix of_node refcount leak in scmi_regulator_probe() scmi_regulator_probe() calls of_find_node_by_name() which takes a reference on the returned device node. On the error path where process_scmi_regulator_of_node() fails, the function returns without calling of_node_put() on the child node, leaking the reference. Add of_node_put(np) on the error path to properly release the reference.

Frequently Asked Questions
What is CVE-2026-64301? +
In the Linux kernel, the following vulnerability has been resolved:
regulator: scmi: fix of_node refcount leak in scmi_regulator_probe()
scmi_regulator_probe() calls of_find_node_by_name() which takes a
reference on the returned device node. On the error path where
process_scmi_regulator_of_node() fails, the function returns without
calling of_node_put() on the child node, leaking the reference.
Add of_node_put(np) on the error path to properly release the
reference.
