Besides shaming, there's one more option -- acknowledgement.

When it's a test case or test tool that discovered the bug, we could
acknowledge it by adding one line in the bug fixing patch. The exact
forms can be discussed, but here are some examples to show the basic
idea:

Tool: lockdep
Tool: ktest
Tool: smatch
Tool: trinity
Tool: syzkaller
Tool: xfstests/tests/ext4/025
Tool: scripts/coccinelle/locks/call_kern.cocci
Tool: tools/testing/selftests/bpf/test_align.c

Reports from test infrastructures like 0day could go further to help
acknowledge the tool author or maintainer by showing such lines in its
bug report email:

You may consider adding these lines in the bug fixing patch:

-----------------------[ cut here ]----------------------------------
Fixes: XXXXXXXXXX ("title of the buggy commit")
Tool: tools/testing/selftests/bpf/test_align.c <davem-fT/PcQaiUtIeIZ0/mPfg9Q@public.gmane.org>
Reported-by: 0day test robot <xiaolong.ye-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>
