After a several month hiatus from Emacs development, I'm now getting two
SIGSYS failures in 'make test/emacs-tests' again on both emacs-28 and
master (ERT backtraces and configuration info follow my signature).

This time, 'sudo journalctl -g SECCOMP' mentions the following:

  Jan 21 15:47:02 tia audit[138481]: SECCOMP auid=1000 uid=1000 gid=1000
    ses=2 subj==unconfined pid=138481 comm="emacs"
    exe="/home/blc/.local/src/emacs-nox/src/emacs" sig=31 arch=c000003e
    syscall=17 compat=0 ip=0x7fd745f3714a code=0x80000000

  Jan 21 15:47:03 tia audit[138493]: SECCOMP auid=1000 uid=1000 gid=1000
    ses=2 subj==unconfined pid=138493 comm="emacs"
    exe="/home/blc/.local/src/emacs-nox/src/emacs" sig=31 arch=c000003e
    syscall=439 compat=0 ip=0x7f46e8c30fc0 code=0x80000000

where AFAICT syscalls 17 and 439 correspond to pread64 and faccessat2,
respectively.  This is again confirmed by the ausearch ert-info when I
run 'sudo make test/emacs-tests':

In contrast to the OP, I am now on Linux 5.15.0-2 and glibc 2.33-2.

HTH.  As always, let me know if you'd like me to test anything.

Thanks,
