Calling mana_detach() again unconditionally leads to NULL pointer dereferences during queue teardown.</p> <p>Add an early exit in mana_detach() when the port is already in detached state (!netif_device_present) for non-close callers, making it safe to call idempotently. This allows the queue reset handler and other recovery paths to simply retry mana_attach() without redundant teardown.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>net: mana: Skip redundant detach on already-detached port</p> <p>When mana_per_port_queue_reset_work_handler() runs after a previous detach succeeded but attach failed, the port is left in a detached state with apc-&gt;tx_qp and apc-&gt;rxqs already freed.
