Description OSIDB Bzimport 2025-02-26 03:12:50 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ARM: versatile: Add missing of_node_put in dcscb_init

The device_node pointer is returned by of_find_compatible_node
with refcount incremented. We should use of_node_put() to avoid
the refcount leak.
