Description OSIDB Bzimport 2025-02-26 03:09:01 UTC

In the Linux kernel, the following vulnerability has been resolved:

ARM: meson: Fix refcount leak in meson_smp_prepare_cpus

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.
