Linux Kernel Memory Leak Vulnerability in ASoC Mediatek MT8195 Driver

A memory leak vulnerability has been identified in the Linux kernel's ASoC Mediatek MT8195 driver. The issue arises during the device probe process, where the device_node pointer, returned by of_parse_phandle() with an incremented reference count, is not properly released. This oversight leads to a reference count leak, as of_node_put() is only called in the normal execution path, leaving the error path unaddressed.

Impact

Exploitation of this vulnerability causes a reference count leak, which can lead to memory management issues.
