CVE-2024-42152 is a race condition in the Linux kernel NVMe target (nvmet) subsystem during queue-pair establishment. If a client disconnects while an NVMe admin connect command is still in an early stage, nvmet_sq_destroy can capture a null controller pointer before the admin-connect handler allocates and assigns the controller. A controller allocated before queue reference confirmation can consequently miss its final reference release, causing the controller and associated resources to leak. The upstream correction re-reads the controller pointer after all in-flight requests complete, ensuring cleanup operates on the final controller reference.
