  "details": "In the Linux kernel, the following vulnerability has been resolved:  accel/ethosu: fix arithmetic issues in dma_length()  dma_length() derives DMA region usage from command stream values and updates region_size[]:      len = ((len + stride[0]) * size0 + stride[1]) * size1     region_size[region] = max(..., len + dma-\u003eoffset)  Several arithmetic issues can corrupt the derived region size:  - signed stride values may underflow when added to len - intermediate multiplications may overflow - len + dma-\u003eoffset may overflow during region_size updates - dma_length() error returns were not validated by the caller  region_size[] is later used by ethosu_job.c to validate command stream accesses against GEM buffer sizes. Arithmetic wraparound can therefore under-report region usage and bypass the bounds validation.  Fix by validating signed additions, using overflow helpers for multiplications and offset updates, and propagating dma_length() failures to the caller.",
