Description
In the Linux kernel, the following vulnerability has been resolved:
device property: fix of node refcount leak in fwnode_graph_get_next_endpoint()
The 'parent' returned by fwnode_graph_get_port_parent()
with refcount incremented when 'prev' is not NULL, it
needs be put when finish using it.
Because the parent is const, introduce a new variable to
store the returned fwnode, then put it before returning
from fwnode_graph_get_next_endpoint().
Affected configurations
• linux linux kernel (>= 5.15 < 5.15.91)
• linux linux kernel (>= 5.16 < 6.1.9)
• linux linux kernel 6.2
