Linux Kernel Refcount Leak Vulnerability in ASoC TI J721E-EVM

A refcount leak vulnerability has been identified in the Linux kernel's ASoC TI J721E-EVM component. The issue arises in the 'j721e_soc_probe_*of_parse_phandle()' function, where a node pointer is returned with an incremented reference count. If the pointer is not needed anymore, the reference count should be decremented using 'of_node_put()' to prevent the leak. The vulnerability has been addressed by adding the missing 'of_node_put()' call.

Impact

Exploitation of this vulnerability could lead to a refcount leak, causing memory management issues.
