"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nx86/mm: Don't apply va_align to hugetlb mappings on AMD F15h\n\nget_align_mask() returns huge_page_mask_align() for hugetlbfs, but get_align_bits()\nadds va_align.bits regardless, so vm_unmapped_area() returns an address off the huge\npage boundary and __unmap_hugepage_range() hits BUG_ON(start & ~huge_page_mask(h)) at\nteardown.\n\nThis can be triggered on Carrizo and FX-8370E, both hstates.\n\nPass the file to get_align_bits() and skip the randomisation for hugetlbfs.\n\n [ bp: Massage commit message. ]"
