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...

In the Linux kernel, the following vulnerability has been resolved: mm/pagealloc: fix initialization of tags of the huge zero folio with initonfree GFPZEROTAGS semantics are currently a bit weird, but effectively this flag is only ever set alongside GFPZERO and GFPSKIPKASAN. If we run with...
