Linux Kernel Memory Leak Vulnerability in ASoC Atmel Component

A memory leak vulnerability has been identified in the Linux kernel's ASoC Atmel component. The issue arises from improper error handling in the 'snd_proto_probe' function, where a device_node pointer returned by 'of_parse_phandle()' is not correctly released in error 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 scenarios as well.

Impact

The vulnerability causes a reference count leak, which can lead to memory management issues.
