Description

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.
