      "title": "accel/ethosu: fix arithmetic issues in dma_length()",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\naccel/ethosu: fix arithmetic issues in dma_length()\n\ndma_length() derives DMA region usage from command stream values and\nupdates region_size[]:\n\n    len = ((len + stride[0]) * size0 + stride[1]) * size1\n    region_size[region] = max(..., len + dma->offset)\n\nSeveral arithmetic issues can corrupt the derived region size:\n\n- signed stride values may underflow when added to len\n- intermediate multiplications may overflow\n- len + dma->offset may overflow during region_size updates\n- dma_length() error returns were not validated by the caller\n\nregion_size[] is later used by ethosu_job.c to validate command stream\naccesses against GEM buffer sizes. Arithmetic wraparound can therefore\nunder-report region usage and bypass the bounds validation.\n\nFix by validating signed additions, using overflow helpers for\nmultiplications and offset updates, and propagating dma_length()\nfailures to the caller.",
