First published: Wed Feb 26 2025(Updated: )
In the Linux kernel, the following vulnerability has been resolved: ARM: Fix refcount leak in axxia_boot_secondary of_find_compatible_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.
