Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-19 15:31

Details

In the Linux kernel, the following vulnerability has been resolved:

mfd: max77620: Fix refcount leak in max77620_initialise_fps

of_get_child_by_name() 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.

Severity

5.5 (Medium)
