Description
A flaw was found in the Linux kernel's NVMe over Fabrics (nvme-fabrics) subsystem. When user tasks issue a large volume of concurrent commands, available command tags in the administrator queue can become exhausted. If a device reset or I/O timeout occurs while these commands are pending, the reconnection routine fails to update controller registers due to tag starvation. This flaw allows a local user to cause an unrecoverable kernel hang, resulting in a Denial of Service (DoS).
