CVE-2024-27407

Memory corruption via wrapped resident attribute size

Published May 17, 2024 · Updated Aug 5, 2026

Buffer overflow in the Linux kernel NTFS3 driver allows attackers to corrupt kernel memory through a crafted NTFS volume. In mi_enum_attr(), adding a resident attribute data size to its offset in 32-bit arithmetic can wrap and bypass the record-size check, enabling out-of-bounds reads and writes. Exploitation requires the malicious volume to be mounted or handled by an automounter and can disclose or overwrite kernel memory or crash the system.
