CVE-2026-64130

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’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...

PT-2026-61447

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the memory management system where the initialization of tags for the huge zero folio is not correctly handled when init on free is enabled. When allocating with the G...

CVE-2025-68292

In the Linux kernel, the following vulnerability has been resolved: mm/memfd: fix information leak in hugetlb folios When allocating hugetlb folios for memfd, three initialization steps are missing: 1. Folios are not zeroed, leading to kernel memory disclosure to userspace 2. Folios are not marke...

CVE-2025-68292

The CVE-2025-68292 issue concerns the Linux kernel memfd hugetlb folio allocation. A path used by memfd bypassed the normal page fault handler (hugetlb_no_page), omitting three initialisation steps that could leak kernel memory or cause races: (1) folios not zeroed, risking information disclosure...

PT-2025-51696

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the Linux kernel's memfd functionality related to hugetlb folios. Specifically, when allocating huge transparent pages for memfd, initialization steps were missing,...
