CVE-2026-80902 (GCVE-0-2026-80902)

Vulnerability from cvelistv5 – Published: 2026-09-04 17:11 – Updated: 2026-09-04 17:11

Title

dmaengine: sun6i-dma: Fix reclaim descriptors while terminating DMA

Summary

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.

Severity

Vulnerability from github – Published: 2026-09-04 18:31 – Updated: 2026-09-04 18:31

Details

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.

  "details": "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-\u003edesc != pchan-\u003edone check to prevent double-adding completed\ndescriptors, which would corrupt the list.",
