In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Fix possible Use-After-Free in irqprocesswork_list
Use listforeachentrysafe() to allow iterating through the list and deleting the entry in the iteration process. The descriptor is freed via idxddesccomplete() and there's a slight chance may cause issue for the list iterator when the descriptor is reused by another thread without it being deleted from the list.
