CVE-2026-68371: usb: musb: omap2430: Do not put borrowed of_node in probe

Published Aug 10, 2026
·
Updated

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

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

omap2430probe() stores pdev->dev.ofnode 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 ofnodeput(np). This drops a reference that is owned by the platform device, and can leave pdev->dev.ofnode with an unbalanced reference count.

Do not put the borrowed platform device node from omap2430probe(). References taken for the child MUSB device are handled by the device core, and the ctrl-module phandle reference is still released separately.
