Overview
CVE-2026-93232 is a known-severity vulnerability. It was published on September 24, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
mm/hugetlb: fix boot panic with CONFIG_DEBUG_VM and HVO bootmem pages
Patch series "mm: Refactor bootmem gigantic hugepage allocation", v4.
This series is split out from the earlier larger series "mm: Generalize
HVO for HugeTLB and device DAX" [1]. It collects the first 19 patches of
that series as a standalone set of fixes and preparatory cleanups around
bootmem HugeTLB handling, sparse initialization ordering, and related
vmemmap setup.
The first patches fix a few bugs found while reviewing the existing code,
including incorrect bootmem HVO handling, wrong vmemmap registration
arguments, a powerpc compound-vmemmap tracking bug, and too-late
initialization of gigantic bootmem HugeTLB struct pages.
The rest of the series reorders early memory initialization so the
relevant zone state is available before sparse and HugeTLB boot-time setup
runs, then simplifies the remaining bootmem gigantic hugepage allocation
