Description OSIDB Bzimport 2025-06-18 12:03:22 UTC 
In the Linux kernel, the following vulnerability has been resolved:

usb: host: Fix refcount leak in ehci_hcd_ppc_of_probe

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