CVE-2024-53235Public exploit

Kernel crash via missing FUSE file pointer

Published Dec 27, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux 6.12 through 6.12.1 allows local users to crash the kernel through an EROFS image backed by FUSE. EROFS erofs_bread passes NULL to read_mapping_folio instead of preserving the backing file pointer required by FUSE read I/O. A low-privileged local user must cause EROFS to read metadata from a FUSE-backed file; successful triggering crashes the kernel without reported data disclosure or modification.
