Thank you for bringing this to my attention.
I have (hopefully) fixed the issue with
commit 00a85a1634 ("umdns: add missing syscalls to seccomp filter"),
at least on my Aarch64 test boards it works now.
More/other syscalls may be needed on different architectures, see
the commit description of the fix mentioned above for instructions on
how to find them.
