This flaw could allow a privileged local user to cause a system crash or other undefined behaviors.", "A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the extra inode size for extended attributes. This flaw allows a privileged local user to cause a system crash or other undefined behaviors." ],
  "statement" : "This flaw has been rated as having Moderate impact because of the preconditions needed to trigger the issue. The vulnerability can be exploited by a regular user, but the filesystem should be mounted with `debug_want_extra_isize`=128 and the user must have write access to the filesystem. It's also important to emphasize that `debug_want_extra_isize` is a debug mount option and should never be used in production.",
