Low risk8th percentile - higher than 8% of all known CVEs
Summary
In the Linux kernel, the usb: musb: omap2430 driver's omap2430_probe() calls of_node_put() on a borrowed of_node pointer, leading to an unbalanced reference count for the platform device node.
Risk Assessment
An unbalanced reference count can lead to premature memory freeing or device lifecycle issues, potentially causing system crashes or instability.
Recommendation
Apply a kernel patch that removes the of_node_put() call for the borrowed node in omap2430_probe().
Original NVD description (English source)
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.
