  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nvirtio-blk: fix implicit overflow on virtio_max_dma_size\n\nThe following codes have an implicit conversion from size_t to u32:\n(u32)max_size = (size_t)virtio_max_dma_size(vdev);\n\nThis may lead overflow, Ex (size_t)4G -> (u32)0. Once\nvirtio_max_dma_size() has a larger size than U32_MAX, use U32_MAX\ninstead.",
