NVD description
In the Linux kernel, the following vulnerability has been resolved: rapidio: clear mport->net when rio_add_net() fails rio_alloc_net() stores the newly allocated rio_net in mport->net before rio_scan_alloc_net() registers the device. If rio_add_net() fails, rio_scan_alloc_net() drops the device reference with put_device(), which releases the rio_net through the device release callback. However, mport->net is left pointing at the freed object. A later mport unregister path can then dereference the dangling mport->net pointer and may try to free the same rio_net again. Clear mport->net in the rio_add_net() failure path, matching the cleanup done for the destID table allocation failure path.
