Description OSIDB Bzimport 2025-12-09 01:02:17 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ARM: zynq: Fix refcount leak in zynq_early_slcr_init

of_find_compatible_node() returns a node pointer with refcount incremented,
we should use of_node_put() on error path.
Add missing of_node_put() to avoid refcount leak.
