CVE-2022-50122 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8173-rt5650: Fix refcount leak in mt8173_rt5650_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 refcount leak in some error paths.
A refcount leak vulnerability has been identified in the Linux kernel's ASoC Mediatek MT8173-RT5650 component. The issue arises in the 'mt8173_rt5650_dev_probeof_parse_phandle()' function, where a node pointer is returned with an incremented reference count. The vulnerability allows for a memory management error, as the reference count is not properly decremented when the node is no longer needed, leading to potential resource leaks. This refcount leak occurs in certain error handling paths of the function.
