      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndmaengine: sun6i-dma: Fix reclaim descriptors while terminating DMA\n\nWhen terminating DMA transfers, active descriptors are not properly\nreclaimed. Only cyclic descriptors were handled, leaving non-cyclic\ndescriptors and their LLI chains to be permanently leaked.\n\nFix by using vchan_terminate_vdesc() which handles both cyclic and\nnon-cyclic descriptors by adding them to desc_terminated queue for\nproper cleanup.\n\nAdd pchan->desc != pchan->done check to prevent double-adding completed\ndescriptors, which would corrupt the list.",
