GHSA-H728-7P3P-F89Q

Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-25 15:31

Details

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

PCI: mediatek-gen3: Fix refcount leak in mtk_pcie_init_irq_domains()

of_get_child_by_name() returns a node pointer with refcount incremented, so we should use of_node_put() on it when we don't need it anymore.

Add missing of_node_put() to avoid refcount leak.

Severity ?

5.5 (Medium)
