Information

The jffs2 (journaling flash filesystem 2) filesystem type is a log-structured filesystem used in flash memory devices.
 Rationale:
 Removing support for unneeded filesystem types reduces the local attack surface of the system. If this filesystem type is not needed, disable it.

Solution

Edit or create a file in the /etc/modprobe.d/ directory ending in .conf
 Example: vim /etc/modprobe.d/jffs2.conf
 and add the following line:
 install jffs2 /bin/true
 Run the following command to unload the jffs2 module:
 # rmmod jffs2
