CVE-2026-93199
i3c: master: Do not treat master device as a duplicate target
Description
In the Linux kernel, the following vulnerability has been resolved: i3c: master: Do not treat master device as a duplicate target i3c_master_search_i3c_dev_duplicate() searches the bus for another I3C device with the same PID as the reference device. The search can match master->this, causing the controller itself to be returned as a duplicate. Since the controller is not a target device, it cannot be a duplicate of one. Exclude master->this from matching so that the function only returns real duplicate target devices.
