Linux Kernel Memory Leak Vulnerability in ASoC Atmel Audio Probe

Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's ASoC Atmel audio probe function for the AT91SAM9G20EK. The issue arises because a node pointer returned by 'of_parse_phandle()' lacks a corresponding 'of_node_put()' call, leading to a reference count leak. The vulnerability has been addressed by adding the missing 'of_node_put()' to prevent the refcount leak.

Impact

The vulnerability could lead to a memory leak, causing increased memory usage over time, which could potentially degrade system performance.
