Description

A flaw was found in the Linux kernel's Non-Volatile Memory Express (NVMe) subsystem. When an NVMe controller is reset, a previously allocated administration queue may not be properly released before a new one is created. This can lead to the old queue becoming orphaned, potentially causing resource exhaustion or system instability over time.
