"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: qrtr: ns: Fix use-after-free in driver remove()\n\nIn the remove callback, if a packet arrives after destroy_workqueue() is\ncalled, but before sock_release(), the qrtr_ns_data_ready() callback will\ntry to queue the work, causing use-after-free issue.\n\nFix this issue by saving the default 'sk_data_ready' callback during\nqrtr_ns_init() and use it to replace the qrtr_ns_data_ready() callback at\nthe start of remove(). This ensures that even if a packet arrives after\ndestroy_workqueue(), the work struct will not be dereferenced.\n\nNote that it is also required to ensure that the RX threads are completed\nbefore destroying the workqueue, because the threads could be using the\nqrtr_ns_data_ready() callback."
