  "details": "In the Linux kernel, the following vulnerability has been resolved:  i3c: master: Fix info leak and UAF in device unregister path  i3c_master_unregister_i3c_devs() clears i3cdev-\u003edev-\u003edesc before calling device_unregister().  During device_unregister(), device_del() emits a KOBJ_REMOVE uevent and unbinds the driver while the device descriptor is still expected to be valid.  As a result, i3c_device_uevent() and a racing modalias_show() can observe a NULL desc and fall back to an uninitialized stack struct i3c_device_info, leaking kernel stack contents in the generated modalias.  Driver .remove() callbacks may also encounter an unexpected NULL desc during unbind.  Keep desc valid until device_unregister() has completed.  Since device_unregister() drops the device reference and may free the device, take an extra reference with get_device() before unregistering.  Clear desc afterwards and release the extra reference with put_device(). This preserves the release-time invariant that desc must be NULL while avoiding both the information leak and a potential use-after-free from writing desc after the device has been released.",
