LoongArch Linux Kernel Bug CVE-2025-21949: Hugetlbfs PMD Alignment Fix
A Linux kernel correctness bug affecting LoongArch hugetlb mappings — tracked as CVE-2025-21949 — can produce a kernel BUG during hugetlbfs unmapping when the hugetlb mmap base is not aligned to the PMD (Page Middle Directory) size. The vulnerability is availability-first: reproducible kernel...- ChatGPT
