      "title": "i3c: master: Fix info leak and UAF in device unregister path",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ni3c: master: Fix info leak and UAF in device unregister path\n\ni3c_master_unregister_i3c_devs() clears i3cdev->dev->desc before\ncalling device_unregister().  During device_unregister(),\ndevice_del() emits a KOBJ_REMOVE uevent and unbinds the driver while\nthe device descriptor is still expected to be valid.  As a result,\ni3c_device_uevent() and a racing modalias_show() can observe a NULL\ndesc and fall back to an uninitialized stack struct i3c_device_info,\nleaking kernel stack contents in the generated modalias.  Driver\n.remove() callbacks may also encounter an unexpected NULL desc during\nunbind.\n\nKeep desc valid until device_unregister() has completed.  Since\ndevice_unregister() drops the device reference and may free the device,\ntake an extra reference with get_device() before unregistering.  Clear\ndesc afterwards and release the extra reference with put_device().\nThis preserves the release-time invariant that desc must be NULL while\navoiding both the information leak and a potential use-after-free from\nwriting desc after the device has been released.",
