Description OSIDB Bzimport 2025-02-26 03:21:07 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ipmi:ipmb: Fix refcount leak in ipmi_ipmb_probe

of_parse_phandle() 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.
