CVE-2025-38084

CVE-2025-38084 affects the Linux kernel mm/hugetlb subsystem. Description: unshare of hugetlb page tables during VMA split occurs too early (before VMA/rmap locks), enabling racing page faults and rmap walks to share page tables before split. The fix: call hugetlb unshare logic from __split_vma()...

CVE-2025-38084 mm/hugetlb: unshare page tables during VMA split, not before

In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: unshare page tables during VMA split, not before Currently, splitvma triggers hugetlb page table unsharing through vmops-maysplit. This happens before the VMA lock and rmap locks are taken - which is too early, it...

CVE-2024-50066

CVE-2024-50066 is a Linux kernel race in mm/mremap where move_page_tables can race with retract_page_tables under THP/rmap locking. The flaw stems from reading the PMD type before acquiring rmap locks, potentially creating bogus PMD entries (e.g., mapping page 0 as a page table on x86) and enabli...
