Description OSIDB Bzimport 2025-02-26 03:25:37 UTC 
In the Linux kernel, the following vulnerability has been resolved:

iio: adc: adi-axi-adc: Fix refcount leak in adi_axi_adc_attach_client

of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
