  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndmaengine: idxd: Fix possible Use-After-Free in irq_process_work_list\n\nUse list_for_each_entry_safe() to allow iterating through the list and\ndeleting the entry in the iteration process. The descriptor is freed via\nidxd_desc_complete() and there's a slight chance may cause issue for\nthe list iterator when the descriptor is reused by another thread\nwithout it being deleted from the list.",
