  "title": "linux: In the Linux kernel, the following vulnerability has been resolved:  parisc: fix a possible DMA corruption  ARCH_DMA_...",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  parisc: fix a possible DMA corruption  ARCH_DMA_MINALIGN was defined as 16 - this is too small - it may be possible that two unrelated 16-byte allocations share a cache line. If one of these allocations is written using DMA and the other is written using cached write, the value that was written with DMA may be corrupted.  This commit changes ARCH_DMA_MINALIGN to be 128 on PA20 and 32 on PA1.1 - that\u0027s the largest possible cache line size.  As different parisc microarchitectures have different cache line size, we define arch_slab_minalign(), cache_line_size() and dma_get_cache_alignment() so that the kernel may tune slab cache parameters dynamically, based on the detected cache line size.",
