      "title": "netdevsim: update queue NAPI association on queue reset",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetdevsim: update queue NAPI association on queue reset\n\nIn netdevsim, receive queues (struct nsim_rq) embed their own struct\nnapi_struct. When queue reset is performed (e.g. via queue_reset\ndebugfs), nsim_queue_start() swaps in a newly allocated struct nsim_rq,\nand nsim_queue_mem_free() later deletes and frees the old one.\n\nHowever, nsim_queue_start() failed to update the queue-to-NAPI mapping\nvia netif_queue_set_napi(). As a result, dev->_rx[idx].napi continued to\npoint to the old NAPI struct. After the old queue was freed, a subsequent\nqueue dump via Netlink (NETDEV_CMD_QUEUE_GET) triggered a KASAN\nslab-use-after-free read in nla_put_napi_id() when accessing\nrxq->napi->napi_id.\n\nFix this by calling netif_queue_set_napi() in nsim_queue_start() to\nassociate the new NAPI with the RX queue, and clear the association\nwith netif_queue_set_napi(..., NULL) in nsim_del_napi() during teardown.",
