Linux Kernel Refcount Leak Vulnerability in ASoC MT6797-MT6351 Component

A refcount leak vulnerability has been identified in the Linux kernel's ASoC MT6797-MT6351 component. The issue arises in the 'mt6797_mt6351_dev_probeof_parse_phandle()' function, which returns a node pointer with an incremented reference count. Failure to properly decrement this reference count when the node is no longer needed leads to a memory leak.

Impact

Exploitation of this vulnerability causes a memory leak by failing to properly manage reference counts, which can lead to increased memory usage and potential degradation of system performance.
