Vulnerability from github – Published: 2025-03-27 18:31 – Updated: 2026-04-18 09:30

Details

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().

Severity

5.5 (Medium)
