CVE-2026-68371

usb: musb: omap2430: Do not put borrowed of_node in probe

State: Published
Severity: 8.4 High

Description

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

usb: musb: omap2430: Do not put borrowed of_node in probe

omap2430_probe() stores pdev->dev.of_node in a local np variable. This is a borrowed pointer and the probe function does not take a reference to it.

The success and error paths nevertheless call of_node_put(np). This drops a reference that is owned by the platform device, and can leave pdev->dev.of_node with an unbalanced reference count.

Do not put the borrowed platform device node from omap2430_probe(). References taken for the child MUSB device are handled by the device core, and the ctrl-module phandle reference is still released separately.
