Technical description

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

irqchip/realtek-rtl: Fix refcount leak in map_interrupts

of_find_node_by_phandle() returns a node pointer with refcount

incremented, we should use of_node_put() on it when not need anymore.

This function doesn't call of_node_put() in error path.

Call of_node_put() directly after of_property_read_u32() to cover

both normal path and error path.

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.
