Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: common: Fix refcount leak in parse_dai_link_info Add missing of_node_put()s before the returns to balance of_node_get()s and of_node_put()s, which may get unbalanced in case the for loop 'for_each_available_child_of_node' returns early.

Executive Summary

This vulnerability is a refcount leak in the Linux kernel's ASoC mediatek common code, specifically in the parse_dai_link_info function. The issue arises because missing of_node_put() calls before return statements cause an imbalance with of_node_get() calls, especially when the for_each_available_child_of_node loop exits early. This leads to resource management problems in the kernel.

Impact Analysis

The refcount leak can cause resource leaks in the kernel, potentially leading to increased memory usage or instability in the affected system. Over time, this could degrade system performance or cause unexpected behavior in audio subsystem components relying on the affected code.
