Description
In the Linux kernel, the following vulnerability has been resolved: ata: pata_octeon_cf: Fix refcount leak in octeon_cf_probe of_find_device_by_node() takes reference, we should use put_device() to release it when not need anymore. Add missing put_device() to avoid refcount leak.
A refcount leak vulnerability has been identified in the Linux kernel's pata_octeon_cf driver. The issue arises in the 'octeon_cf_probeof_find_device_by_node' function, which improperly manages device reference counts. The function takes a device reference but fails to release it when no longer needed, leading to a memory management issue.
