I noticed in my system logs that the hardening parameter IPAddressDeny has an incorrect value:
bal. 18 10:58:40 systemd[1]: /usr/lib/systemd/system/earlyoom.service:41: Invalid address prefix is specified in [Service] IPAddressDeny=, ignoring assignment: true
It's not a boolean but a list of IP addresses or predefined symbolic names (according to https://www.freedesktop.org/software/systemd/man/latest/systemd.resource-control.html#IPAddressAllow=ADDRESS%5B/PREFIXLENGTH%5D%E2%80%A6).
I set it to
any
which means 0.0.0.0/0 which basically blocks all network access.
