{
    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: adc: ti-adc161s626: use DMA-safe memory for spi_read()\n\nAdd a DMA-safe buffer and use it for spi_read() instead of a stack\nmemory. All SPI buffers must be DMA-safe.\n\nSince we only need up to 3 bytes, we just use a u8[] instead of __be16\nand __be32 and change the conversion functions appropriately.",
