CVE-2024-45024

Local service interruption via mismatched page-table locks

Published Sep 11, 2024 · Updated Aug 5, 2026

Improper locking in Linux 6.10 allows local users to interrupt service by racing GUP against hugetlb page-table updates. GUP takes a PTE or PMD table lock while concurrent hugetlb updates take mm->page_table_lock, leaving the same entries protected by different locks under split locking. Exploitation requires local low-privilege access and a hugetlb folio spanning multiple PTEs or PMDs; the demonstrated result is a kernel warning and service interruption.
