CVE-2026-64130

CVE-2026-64130 concerns the Linux kernel’s memory-tagging handling in mm/page_alloc for the huge zero folio when init_on_free is enabled. The root cause was that __GFP_ZEROTAGS could skip clearing tag memory while __GFP_ZERO and __GFP_SKIP_KASAN were set, leaving leftover MTE tags on pages mapped...
