Description

- In the Linux kernel, the following vulnerability has been resolved: dm: fix race when loading and
unloading a table If the userspace calls two concurrent table load ioctls and one of them succeeds and the
other fails, there is a race condition because dm_setup_md_queue walks &md->table_devices without any
lock. If the walk races with dm_table_destroy -> free_devices -> dm_put_table_device, there is access to
invalid memory. Fix this race by extending the lock over the list walk. (CVE-2026-89998)
