CVE-2026-64130 mm/page_alloc: fix initialization of tags of the huge zero folio with init_on_free

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...

CVE-2026-64130

CVE-2026-64130 concerns the Linux kernel memory tagging during allocation of huge zero folios. The issue arises when init_on_free and __GFP_ZEROTAGS are used together: during __free_pages_prepare() pages may be zeroed while allocations with __GFP_ZEROTAGS skip clearing tag memory, and for huge ze...
