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()...
