CVE-2026-93199

A flaw was found in the Linux kernel's I3C master driver. The i3c_master_search_i3c_dev_duplicate() function, which is designed to identify duplicate I3C target devices, could incorrectly identify the I3C master controller itself as a duplicate. This occurs because the function matches the controller's Process ID (PID) during its search. This incorrect identification could lead to unexpected behavior in the I3C bus operation.
