CVE-2026-80902CVE-2026-80902
Description
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.
