"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndmaengine: idxd: Fix double free in idxd_setup_wqs()\n\nThe clean up in idxd_setup_wqs() has had a couple bugs because the error\nhandling is a bit subtle. It's simpler to just re-write it in a cleaner\nway. The issues here are:\n\n1) If \"idxd->max_wqs\" is <= 0 then we call put_device(conf_dev) when\n \"conf_dev\" hasn't been initialized.\n2) If kzalloc_node() fails then again \"conf_dev\" is invalid. It's\n either uninitialized or it points to the \"conf_dev\" from the\n previous iteration so it leads to a double free.\n\nIt's better to free partial loop iterations within the loop and then\nthe unwinding at the end can handle whole loop iterations. I also\nrenamed the labels to describe what the goto does and not where the goto\nwas located."
