      "title": "firmware: arm_scmi: Fix SCMI device destroy lifetimes",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nfirmware: arm_scmi: Fix SCMI device destroy lifetimes\n\nscmi_child_dev_find() drops the reference returned by\ndevice_find_child() before returning the scmi_device pointer. A\nconcurrent unregister can then release the device while the destroy path\nis still using the returned pointer.\n\nMake the lookup helper return the device_find_child() reference and keep\nit until scmi_device_destroy() has finished unregistering the child.\n\nAlso split device_unregister() in __scmi_device_destroy() so the SCMI bus\nID is not made reusable until after device_del() has removed the old\nscmi_dev.N name from sysfs. This avoids a new SCMI device reusing the\nsame ID while the old device is still registered.\n\nThe final device release callback is also a possible cleanup path when\nSCMI children are deleted by driver core recursion rather than\n__scmi_device_destroy(). Release the SCMI bus ID from a common helper\nused by destroy, register-failure and final-release paths, and clear\nscmi_dev->id after freeing it so the final release cannot free the same\nID again.",
