A vulnerability in the Linux kernel's nvmet subsystem was resolved involving improper copying of the hostid into the controller structure before creating persistent reservation (PR) pc_refs. This caused the hostid used for matching preempted registrants to be a nil UUID, preventing correct identification and handling of in-flight I/O during Preempt and Abort operations. As a result, Preempt and Abort silently degraded to plain Preempt, potentially leaving victim I/O unhandled during reconnects. The fix involves copying the hostid earlier in the connection process before the controller is published and before the snapshot for reservations is taken.
