CVE-2022-49213 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ath10k: Fix error handling in ath10k_setup_msa_resources

The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done.

This function only calls of_node_put() in the regular path. And it will cause refcount leak in error path.
