  "details": "In the Linux kernel, the following vulnerability has been resolved:  misc: fastrpc: fix DMA address corruption due to find_vma misuse  fastrpc_get_args() uses find_vma() to look up the VMA for a user-provided pointer and compute a DMA address offset. When the address falls in a gap before the returned VMA, (ptr \u0026 PAGE_MASK) - vma-\u003evm_start underflows, corrupting the DMA address sent to the DSP.  Replace find_vma() with vma_lookup(), which returns NULL when the address is not contained within any VMA.",
