InformationThe squashfs filesystem type is a compressed read-only Linux filesystem embedded in small footprint systems (similar to cramfs ). A squashfs image can be used without having to first decompress the image.
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
Example: vi /etc/modprobe.d/squashfs.conf
and add the following line:
install squashfs /bin/true
Run the following command to unload the squashfs module:
# rmmod squashfs
