The hfsplus filesystem type is a hierarchical filesystem designed to replace hfs that allows you to mount Mac OS filesystems.
Removing support for unneeded filesystem types reduces the local attack surface of the system. If this filesystem type is not needed, disable it.
None noted.
# modprobe -n -v hfsplus | grep -E '(hfsplus|install)'
# lsmod | grep hfsplus
install /bin/true
The lsmod command should return no output.
# Edit or create a file in the /etc/modprobe.d/ directory ending in .conf
# Example: vi /etc/modprobe.d/hfsplus.conf
# and add the following line:
install hfsplus /bin/true
# Run the following command to unload the hfsplus module:
rmmod hfsplus
Not disabled by default.
