  "title": "of: unittest: fix use-after-free in testdrv_probe()",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  of: unittest: fix use-after-free in testdrv_probe()  The function testdrv_probe() retrieves the device_node from the PCI device, applies an overlay, and then immediately calls of_node_put(dn). This releases the reference held by the PCI core, potentially freeing the node if the reference count drops to zero. Later, the same freed pointer \u0027dn\u0027 is passed to of_platform_default_populate(), leading to a use-after-free.  The reference to pdev-\u003Edev.of_node is owned by the device model and should not be released by the driver. Remove the erroneous of_node_put() to prevent premature freeing.",
