Description OSIDB Bzimport 2025-10-01 12:04:08 UTC 
In the Linux kernel, the following vulnerability has been resolved:

memory: of: Fix refcount leak bug in of_lpddr3_get_ddr_timings()

We should add the of_node_put() when breaking out of
for_each_child_of_node() as it will automatically increase
and decrease the refcount.
