Linux Kernel Refcount Leak Vulnerability in ASoC Mediatek MT8192-MT6359

Vulnerability

A refcount leak vulnerability has been identified in the Linux kernel's ASoC Mediatek MT8192-MT6359 component. The issue arises because the device_node pointer, returned by of_parse_phandle() with an incremented refcount, is not properly released in error handling paths. This oversight can lead to a refcount leak. The vulnerability has been addressed by ensuring that of_node_put() is called in error handling as well.

Impact

The vulnerability could lead to a refcount leak, potentially causing memory management issues.
