CVE-2026-64301 Details
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.
A reference count leak vulnerability has been identified in the Linux kernel's SCMI regulator driver. The issue arises in the 'scmi_regulator_probe()' function, which calls 'of_find_node_by_name()' to retrieve a device node, thereby increasing the reference count. However, if 'process_scmi_regulator_of_node()' encounters an error, the function exits without decrementing the reference count for the child node, leading to a memory leak. This vulnerability affects the Linux kernel stable tree.
The vulnerability has been addressed in the Linux kernel. Users can upgrade to the latest version of the stable kernel to apply the fix.
