Description
Description
In the Linux kernel, the following vulnerability has been resolved:
ASoC: mediatek: mt8173: Fix refcount leak in mt8173_rt5650_rt5676_dev_probe
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Fix missing of_node_put() in error paths.

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a reference count leak in the Linux kernel's ASoC mediatek mt8173 driver. Specifically, the function of_parse_phandle() returns a node pointer with its reference count incremented, but the code did not properly decrement the reference count using of_node_put() in error paths, leading to a leak.
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 if the affected driver is used.
