      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nx86/fred: Correct speculative safety in fred_extint()\n\narray_index_nospec() is no use if the result gets spilled to the stack, as\nit makes the believed safe-under-speculation value subject to memory\npredictions.\n\nFor all practical purposes, this means array_index_nospec() must be used in\nthe expression that accesses the array.\n\nAs the code currently stands, it's the wrong side of irqentry_enter(), and\n'index' is put into %ebp across the function call.\n\nRemove the index variable and reposition array_index_nospec(), so it's\ncalculated immediately before the array access.",
