InformationThe jffs2 (journaling flash filesystem 2) filesystem type is a log-structured filesystem used in flash memory devices.
Removing support for unneeded filesystem types reduces the local attack surface of the system. If this filesystem type is not needed, disable it.
SolutionEdit or create a file in the /etc/modprobe.d/ directory ending in .conf
Add the following line:
install jffs2 /bin/true
Run the following command to unload the jffs2 module:
# rmmod jffs2
