Description OSIDB Bzimport 2025-06-18 12:02:29 UTC 
In the Linux kernel, the following vulnerability has been resolved:

usb: ohci-nxp: Fix refcount leak in ohci_hcd_nxp_probe

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.
