Technical description

In the Linux kernel, the following vulnerability has been resolved:

usb: typec: tcpci: fix of node refcount leak in tcpci_register_port()

I got the following report while doing device(mt6370-tcpc) load

test with CONFIG_OF_UNITTEST and CONFIG_OF_DYNAMIC enabled:

OF: ERROR: memory leak, expected refcount 1 instead of 2,

of_node_get()/of_node_put() unbalanced - destroy cset entry:

attach overlay node /i2c/pmic@34/tcpc/connector

The 'fwnode' set in tcpci_parse_config() which is called

in tcpci_register_port(), its node refcount is increased

in device_get_named_child_node(). It needs be put while

exiting, so call fwnode_handle_put() in the error path of

tcpci_register_port() and in tcpci_unregister_port() to

avoid leak.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
