In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
dmaengine: sun6i-dma: Fix reclaim descriptors while terminating DMA<\/p>\n
When 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.<\/p>\n
Fix by using vchan_terminate_vdesc() which handles both cyclic and
\nnon-cyclic descriptors by adding them to desc_terminated queue for
\nproper cleanup.<\/p>\n
Add pchan->desc != pchan->done check to prevent double-adding completed
\ndescriptors, which would corrupt the list.<\/p>\n","protected":false},"excerpt":{"rendered":"
