Summary
CVE-2022-49342 is a vulnerability affecting the Linux kernel. A refcount leak was identified in the net: ethernet: bgmac driver, specifically in the function bcma_mdio_mii_register. The issue arises from the failure to use of_node_put() to release a node pointer obtained with of_get_child_by_name(). This oversight results in a refcount leak, potentially leading to resource exhaustion or other unintended consequences. The vulnerability has been addressed by adding the missing of_node_put() call to mitigate its impact.
