CVE-2026-90200

CVE-2026-90200 affects the Linux kernel NTFS3 filesystem driver (fs/ntfs3). In ntfs_init_from_boot(), the MFT cluster numbers (mlcn, mlcn2) read from the boot sector are validated via a u64 multiplication against the volume size. A sufficiently large value (e.g., near 2^62) causes the multiplicat...
