CVE-2024-39298

Kernel panic via hugetlb buddy-state race

Published Jun 25, 2024 · Updated May 11, 2026

A race in Linux kernel memory-failure handling allows local users to trigger a kernel panic during hugetlb page recovery. In __page_handle_poison, drain_all_pages can race with compaction after dissolve_free_hugetlb_folio, so take_page_off_buddy fails while a dissolved page is temporarily isolated and later returns with invalid buddy metadata. Local low-privileged access and the race window are required; the demonstrated consequence is a host crash, without reported data disclosure or modification.
