CVE-2024-27435 is a denial-of-service flaw in the Linux kernel NVMe subsystem affecting NVMe over RDMA controller recovery. During controller reset, the admin queue can be quiesced while a keep-alive request retains the sole reserved tag. Because the fabrics queue shares the admin queue tag set, a subsequent reconnect requires a reserved tag for the connect command but cannot obtain one. This circular resource dependency prevents admin-queue reconnection indefinitely even when the remote target and network are healthy. The upstream fix retains two reserved tags for the admin queue.
