CVE-2022-49752

Summary

CVE-2022-49752 is a vulnerability affecting the Linux kernel that has been addressed. The issue involved a refcount leak in the function fwnode_graph_get_next_endpoint(). When 'parent' was returned by fwnode_graph_get_port_parent() with its refcount incremented, it was not properly put away after use. Since 'parent' is a const variable, a new variable was introduced to store the returned fwnode, and this new variable was placed before the function returned from fwnode_graph_get_next_endpoint(). This resolution prevents potential memory leaks and associated security risks.
