Description
In the Linux kernel, the following vulnerability has been resolved: remoteproc: k3-r5: Fix refcount leak in k3_r5_cluster_of_init Every iteration of for_each_available_child_of_node() decrements the reference count of the previous node. When breaking early from a for_each_available_child_of_node() loop, we need to explicitly call of_node_put() on the child node. Add missing of_node_put() to avoid refcount leak.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a reference count leak in the Linux kernel's remoteproc subsystem, specifically in the k3-r5 cluster initialization code. The issue occurs because the code does not properly release references to device tree nodes when breaking early from a loop that iterates over child nodes, leading to a leak of reference counts.


How can this vulnerability impact me? :

The reference count leak can lead to resource leaks in the kernel, potentially causing increased memory usage or instability over time. However, the exact impact depends on the usage of the affected code path and may not directly lead to immediate security breaches.
