In the Linux kernel, the following vulnerability has been resolved:
nilfs2: reject invalid file types when reading inodes
To prevent inodes with invalid file types from tripping through the vfs
and causing malfunctions or assertion failures, add a missing sanity check
when reading an inode from a block device. If the file type is not valid,
treat it as a filesystem error.
