Overview
CVE-2026-93199 is a known-severity vulnerability. It was published on September 17, 2026.
Technical 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.
