MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/3039 JIRA: https://redhat.atlassian.net/browse/RHEL-222295 commit f112ea910e554d58b4b39a4492b7d302f0f4204f Author: Alexander Usyskin <alexander.usyskin@intel.com> Date: Sun Jul 5 18:12:59 2026 +0300 mei: bus: access mei_device under device_lock on cleanup Fix couple of problems in mei_cl_bus_dev_release(): mei_cl_flush_queues() is running without lock. bus->file_list access after mei_dev_bus_put(bus) can become a use-after-free if this was the last reference to bus. Protect queues cleanup and WARN traversal by device lock there to avoid the concurrent access problems. Move WARN traversal before mei_dev_bus_put(bus). This file uses bus variable name for mei_device, adjust code of mei_cl_bus_dev_release() to use bus variable too.
