In the Linux kernel, the following vulnerability has been resolved: dmaengine: sun6i-dma: Fix reclaim descriptors while terminating DMA When terminating DMA transfers, active descriptors are not properly reclaimed. Only cyclic descriptors were handled, leaving non-cyclic descriptors and their LLI chains to be permanently leaked. Fix by using vchan_terminate_vdesc() which handles both cyclic and non-cyclic descriptors by adding them to desc_terminated queue for proper cleanup. Add pchan->desc != pchan->done check to prevent double-adding completed descriptors, which would corrupt the list.
