  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\npstore/ram: Fix crash when setting number of cpus to an odd number\n\nWhen the number of cpu cores is adjusted to 7 or other odd numbers,\nthe zone size will become an odd number.\nThe address of the zone will become:\n    addr of zone0 = BASE\n    addr of zone1 = BASE + zone_size\n    addr of zone2 = BASE + zone_size*2\n    ...\nThe address of zone1/3/5/7 will be mapped to non-alignment va.\nEventually crashes will occur when accessing these va.\n\nSo, use ALIGN_DOWN() to make sure the zone size is even\nto avoid this bug.",
